1. Unit Heaters (Gas or Electric)

• Ceiling- or wall-mounted, blowing warm air directly.

• Good for spot heating or small/medium warehouses.

• Low upfront cost, but not the most efficient for large spaces.

2. Infrared (Radiant Tube or Panel Heaters)

• Heat objects, floors, and people instead of just the air.

• Great for tall ceilings or drafty warehouses since warm air doesn’t rise and get wasted.

• Common in loading docks and large open areas.

3. Rooftop HVAC Units (RTUs)

• Packaged heating/cooling systems mounted on the roof.

• Efficient for larger warehouses that also need cooling in summer.

• Higher upfront cost, but centralized and easier for large distribution centers.

4. Hydronic Heating (Hot Water or Steam Radiators / Radiant Floor)

• Uses boilers to circulate hot water or steam.

• Radiant floor heating is extremely comfortable and efficient, but costly and better for new construction.

• Great for facilities that need consistent temperatures.

5. Make-Up Air Units (MAUs)

• Provide fresh, tempered air for warehouses with exhaust systems (factories, industrial).

• Often paired with other heating systems.

1. Walk-In Cooler

• Temperature Range: ~35°F to 45°F (just above freezing).

• Purpose: Keeps food, beverages, or products fresh without freezing.

• Refrigeration Setup:

• Medium-temperature compressor (typically uses refrigerants like R-448A, R-449A, R-404A, or CO₂ in modern systems).

• Evaporator coil inside the cooler to absorb heat.

• Condensing unit (air- or water-cooled) that rejects heat to outside.

• Expansion device (TXV or EEV) to meter refrigerant.

• Insulation: ~4 inches thick (polyurethane or polystyrene panels).

• Defrost: Often just off-cycle defrost (system shuts off, coil warms up naturally).

👉 Common in restaurants, grocery stores, beverage storage.

2. Walk-In Freezer

• Temperature Range: ~0°F to –10°F (sometimes colder for special storage).

• Purpose: Freezes and preserves food or products long-term.

• Refrigeration Setup:

• Low-temperature compressor (bigger, works harder to pull temps down).

• Evaporator coil designed for lower temps, often with electric heaters for defrost.

• Condensing unit sized for higher load since freezers have more heat infiltration.

• Expansion device sized for lower temp/pressure refrigerant flow.

• Insulation: At least 6 inches thick, with heated door frames and sometimes heated floors to prevent ice buildup.

• Defrost: Requires active defrost (electric heaters, hot gas, or water).

👉 Common in butcher shops, warehouses, food distribution, ice cream storage.
