H&C Coil Evaporators

• Maintaining low temperatures in walk-in chillers and freezers for food storage.
• Providing refrigeration for pharmaceutical storage facilities.
• Cooling controlled environments in agricultural settings, such as flower or produce storage.
• Used in various industrial processes requiring precise temperature control within an enclosed space.

Typical cooling capacity

For this class of equipment, cooling capacities typically range from 5 kW to 30 kW, depending on the specific model and application.

Power supply

Commonly, units of this type operate on 400V, 3-phase power, though smaller models may use 230V, 1-phase.

Refrigerant compatibility

Modern H&C coil evaporators are typically designed for use with HFC or HFO refrigerants, such as R404A, R407C, or R448A/R449A.

Defrost method

Units commonly feature electric defrost, hot gas defrost, or air defrost, with electric defrost being prevalent for freezer applications.

Fan type

Axial fans are typically used for efficient air circulation within the cold room.

Construction material

Coils are typically copper or aluminium, with casings often made from powder-coated galvanised steel or aluminium for durability and corrosion resistance.

• What does 'dual coil' mean for an evaporator?

  A dual coil configuration typically means the evaporator has two separate refrigerant circuits or two distinct coil sections, which can offer increased capacity or redundancy.

• How do I determine if this evaporator is suitable for my existing cold room?

• What maintenance is typically required for H&C coil evaporators?

• Can this used evaporator be adapted for different refrigerants?

• What are the common causes of reduced efficiency in an evaporator?

Cold rooms and refrigeration units are considered essential assets in food processing operations. Buyers typically prioritise reliability, energy efficiency, and ease of maintenance when selecting used models. Industry sentiment favours equipment from reputable manufacturers known for durability. Key considerations include checking refrigerant systems, insulation condition, and temperature consistency. Well-maintained units often deliver strong performance at reduced cost compared to new alternatives, making them attractive for budget-conscious operations seeking dependable temperature control.
