HVAC Equipment Cases: AHRI 210/240 & ASHRAE

A Carrier 30XA air-cooled liquid chiller compressor module ($85,000-$150,000) shipped from a manufacturing facility in Monterrey to a mechanical contractor in Chicago arrived with a damaged compressor discharge valve. The cause? A standard steel shipping crate with 25mm of loose-fill polystyrene that shifted during truck transport, allowing the 450kg module to move 20mm inside the crate and impact the crate wall during a 12g handling drop at the construction site. The repair required a replacement discharge valve ($4,200), a full refrigerant recovery and recharge ($2,800 in labor and materials), and a 5-day delay in the building’s commissioning schedule. The building’s delay cost was $15,000 per day (a typical commercial building project has $10,000-$25,000 per day in delay costs, including construction financing, insurance, and lost revenue)—so the total cost of that damaged discharge valve was $82,000.

HVAC (Heating, Ventilation, and Air Conditioning) equipment spans the entire building services chain: from chillers and cooling towers that provide cooling, to boilers and heat pumps that provide heating, to air handling units (AHUs) and fan coil units (FCUs) that distribute conditioned air, to variable refrigerant flow (VRF) systems and ductless mini-splits that provide zoned comfort, to building automation systems (BAS) and controls that manage HVAC operation, to refrigeration equipment for commercial and industrial applications. What unites them is that every component is part of a system where a single failure can cause a building outage (which can cost $5,000-$50,000 per day for commercial buildings), a comfort complaint (from tenants or occupants), or in extreme cases, a health and safety issue (from extreme temperatures or poor indoor air quality). The transit case isn’t packaging—it’s the first line of defense against equipment damage during transport, and it must be specified to the same engineering rigor as the equipment it protects.

Regulatory Framework: AHRI, ASHRAE, and Energy Standards

HVAC equipment transport cases must support compliance with a complex web of standards. For performance rating, AHRI 210/240 (Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment) specifies performance rating methods for unitary air-conditioning and air-source heat pump equipment, including SEER (Seasonal Energy Efficiency Ratio), EER (Energy Efficiency Ratio), and HSPF (Heating Seasonal Performance Factor). The transit case must protect equipment without compromising its performance rating (which can be affected by damage to compressors, heat exchangers, or refrigerant systems during transport). For design and installation, ASHRAE Handbook—HVAC Systems and Equipment specifies design and installation requirements for HVAC systems and equipment, and the transit case must support the documentation chain required by ASHRAE standards (including installation manuals, operation and maintenance manuals, and warranty documentation).

For energy efficiency, ASHRAE 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings) specifies minimum energy efficiency requirements for buildings, including HVAC equipment, and the transit case must protect equipment without compromising its energy efficiency rating (which can be affected by damage to compressors, heat exchangers, or controls during transport). For refrigerant management, EPA Section 608 (Protection of Stratospheric Ozone) specifies requirements for refrigerant management, including technician certification, refrigerant recovery, and leak repair, and the transit case must protect refrigerant systems without causing leaks (which can result in EPA fines of up to $44,539 per day per violation, as of 2024). For vibration and noise, AHRI 260 (Sound Rating of Outdoor Unitary Air-Conditioning and Heat Pump Equipment) specifies sound rating methods for outdoor unitary equipment, and the transit case must protect equipment without compromising its sound rating (which can be affected by damage to compressors, fans, or sheet metal during transport). For building automation, BACnet (Building Automation and Control Networks) and Modbus specify communication protocols for building automation systems, and the transit case must protect BAS controllers and sensors without compromising their communication capabilities (which can be affected by ESD damage or connector damage during transport). For refrigeration, AHRI 420 (Performance Rating of Unitary Air-Conditioners and Heat Pumps) and ASHRAE 15 (Safety Code for Mechanical Refrigeration) specify requirements for refrigeration equipment, and the transit case must protect refrigeration equipment without compromising its safety or performance (which can be affected by damage to compressors, evaporators, condensers, or refrigerant systems during transport).

Chillers, AHUs, and VRF Systems: Core Equipment Transport

Chillers and compressor modules (air-cooled chillers, water-cooled chillers, scroll compressors, screw compressors, centrifugal compressors, compressor modules) are typically shipped as complete units with compressors, condensers, evaporators, expansion valves, control systems, and documentation. The most critical areas are: compressors (which can have precision components with tolerances of ±0.005mm, and must not be damaged by impact or by vibration, causing compressor failure or reduced efficiency), refrigerant systems (which must not leak during transport, as refrigerant leaks can result in EPA fines and equipment damage), and control systems (which can have ESD-sensitive components that must not be damaged by electrostatic discharge as low as 50V). Our chiller and compressor module cases use: compressor protection (custom foam with zero-contact foam on compressor bodies, and custom compressor locks to prevent compressor movement during transport), refrigerant protection (custom foam with zero-contact foam on refrigerant lines and components, and custom caps for all refrigerant ports to prevent leaks and contamination), ESD-safe foam (surface resistance 10^6-10^9 Ω/sq) for all electronic components, and shock-isolated sub-crates (wire rope isolators, natural frequency 5-8 Hz, for chiller compressor modules that can weigh 500-5,000kg).

Air handling units (AHUs) and fan coil units (FCUs) (AHUs, FCUs, rooftop units (RTUs), package units, make-up air units, energy recovery ventilators (ERVs)) are typically shipped as complete units with fans, coils, filters, dampers, control systems, and documentation. The most critical areas are: fans (which can have precision-balanced impellers that must not be damaged by impact or by vibration, causing fan imbalance or noise), coils (which can have precision-machined tubes and fins that must not be damaged by impact or by compression, causing coil leaks or reduced heat transfer), and sheet metal (which can be dented or deformed by impact or compression, causing air leaks or reduced performance). Our AHU and FCU cases use: fan protection (custom foam with zero-contact foam on fan impellers and motors, and custom fan locks to prevent fan movement during transport), coil protection (custom foam with zero-contact foam on coil surfaces, and custom coil protectors to prevent damage), sheet metal protection (custom foam with zero-contact foam on sheet metal surfaces, and custom sheet metal protectors to prevent denting or deformation), and IP65 sealing (continuous silicone gaskets, for protection against dust and moisture during transport and storage at construction sites, which are often outdoors for 3-6 months before installation). VRF (Variable Refrigerant Flow) systems and ductless mini-splits (VRF outdoor units, VRF indoor units, mini-split outdoor units, mini-split indoor units, branch selector boxes, refrigerant piping kits) are typically shipped as complete systems with outdoor units, indoor units, controls, and documentation. The most critical areas are: compressors (which can have precision components with tolerances of ±0.005mm, and must not be damaged by impact or by vibration), refrigerant systems (which must not leak during transport, as refrigerant leaks can result in EPA fines and equipment damage), and ESD-sensitive components (which can be damaged by electrostatic discharge as low as 50V). Our VRF and mini-split cases use: compressor protection (custom foam with zero-contact foam on compressor bodies, and custom compressor locks to prevent compressor movement during transport), refrigerant protection (custom foam with zero-contact foam on refrigerant lines and components, and custom caps for all refrigerant ports to prevent leaks and contamination), ESD-safe foam (surface resistance 10^6-10^9 Ω/sq) for all electronic components, and IP65 sealing (continuous silicone gaskets, for protection against dust and moisture during transport and storage).

Boilers, BAS Controllers, and Refrigeration Equipment: Specialized Transport Requirements

Boilers and heat pumps (gas boilers, oil boilers, electric boilers, heat pumps, geothermal heat pumps, solar thermal systems) are typically shipped as complete units with burners, heat exchangers, pumps, expansion tanks, control systems, and documentation. The most critical areas are: burners (which can have precision components that must not be damaged by impact or by contamination, causing burner failure or inefficient combustion), heat exchangers (which can have precision-machined tubes and fins that must not be damaged by impact or by compression, causing heat exchanger leaks or reduced efficiency), and control systems (which can have ESD-sensitive components that must not be damaged by electrostatic discharge as low as 50V). Our boiler and heat pump cases use: burner protection (custom foam with zero-contact foam on burner components, and custom burner protectors to prevent damage and contamination), heat exchanger protection (custom foam with zero-contact foam on heat exchanger surfaces, and custom heat exchanger protectors to prevent damage), ESD-safe foam (surface resistance 10^6-10^9 Ω/sq) for all electronic components, and IP65 sealing (continuous silicone gaskets, for protection against dust and moisture during transport and storage).

BAS (Building Automation System) controllers and sensors (BAS controllers, DDC (Direct Digital Control) controllers, thermostats, temperature sensors, humidity sensors, CO2 sensors, occupancy sensors, actuators, valves) are typically shipped as complete units with mounting hardware and documentation. The most critical areas are: ESD-sensitive components (which can be damaged by electrostatic discharge as low as 50V), connector pins (which can be bent or broken by impact or by improper support), and calibration (sensors require precise calibration of measurement ranges, zero points, and span, which can be affected by vibration during transport). Our BAS controller and sensor cases use: ESD-safe foam (surface resistance 10^6-10^9 Ω/sq) for all electronic components, connector protection (custom foam caps or plastic caps for all connector pins and communication ports), calibration protection (custom foam that holds each sensor in its calibrated position, with zero-contact foam on all precision adjustment mechanisms), and tamper-evident seals (for chain-of-custody documentation—since BAS equipment must be installed and commissioned by certified personnel). Refrigeration equipment (commercial refrigerators, freezers, walk-in coolers, walk-in freezers, display cases, ice machines, refrigerated transport units) are typically shipped as complete units with compressors, evaporators, condensers, expansion valves, control systems, and documentation. The most critical areas are: compressors (which can have precision components with tolerances of ±0.005mm, and must not be damaged by impact or by vibration), refrigerant systems (which must not leak during transport, as refrigerant leaks can result in EPA fines and equipment damage), and evaporators/condensers (which can have precision-machined tubes and fins that must not be damaged by impact or by compression, causing leaks or reduced heat transfer). Our refrigeration equipment cases use: compressor protection (custom foam with zero-contact foam on compressor bodies, and custom compressor locks to prevent compressor movement during transport), refrigerant protection (custom foam with zero-contact foam on refrigerant lines and components, and custom caps for all refrigerant ports to prevent leaks and contamination), evaporator/condenser protection (custom foam with zero-contact foam on evaporator and condenser surfaces, and custom protectors to prevent damage), and IP65 sealing (continuous silicone gaskets, for protection against dust and moisture during transport and storage).

Case Design Specifications and OEM/ODM Capabilities

Our standard HVAC equipment case specification includes: 2mm thick 5052-H32 aluminum panels (or 3mm for heavy-duty applications over 50kg payload, or 4mm for chiller compressor modules that must meet structural requirements), Type II anodized (15-25μm) plus polyester TGIC powder coating (60-80μm) in matte black, gray, or custom color; continuous silicone gaskets (Shore A 50-60) providing IP65 sealing (IP67 available as option); 304 or 316 stainless steel hardware (latches, hinges, handles, rivets)—316 stainless steel is preferred for outdoor and coastal applications, as it is more corrosion-resistant in saltwater environments; CNC-cut closed-cell XLPE foam (40-80 kg/m³, customer-specified density based on payload weight and fragility) with ESD-safe option (surface resistance 10^6-10^9 Ω/sq); heavy-duty draw latches (Southco or equivalent) with rubber bumpers; folding side handles (for cases over 15kg) or top handle (for cases under 15kg); stacking corners (recessed, for secure stacking); and a waterproof document holder (A4 size, inside lid).

Every HVAC equipment case we build is custom-sized to your equipment’s exact dimensions, with CNC-cut foam cavities that hold each component in its operational orientation. We don’t sell stock cases for HVAC equipment—because a 5mm gap means 5mm of potential movement during transport, and that’s where compressor damage, refrigerant leaks, and sheet metal damage start.
