Pipe Water In – Water Out
This section features the connection points for the unit’s water inlet and outlet, designed for systems requiring water-based cooling or heat exchange. The connections are engineered for a secure, robust fit and include a clearly labeled “Water In” position to ensure precise and accurate in
The Direct Expansion (DX) Coil is an evaporator coil in a vapor-compression refrigeration cycle, constituting a direct cooling system.
Mechanism: Low-pressure, low-temperature refrigerant is metered into the coil, where it directly absorbs heat from the passing air and undergoes a phase change (expansion) into a gas before being compressed and condensed in an external unit.
Stainless steel drain pan
Corrosion-resistant drain pan to collect condensate under cooling coils.
2-layer water tray for large machines
