The temperature of the coolant is important to measure the temperature of the coolant at the inlet of the process or equipment. As the coolant travels from the cooler to the process, the temperature may rise. Farther, the higher the potential for thermal gain. Through the insulation cooling line, you can minimize the increase in heat. By minimizing the thermal gain by keeping the cooler as close as possible to the cooled equipment or process.

This is the heat that needs to be removed. Usually in BTU / hour or sometimes watts. The heat load is most often provided, but if not, it can be calculated: heat load = flow rate x fluid density x fluid specific heat x constant xΔT°.

Coolant flow and pressure. These parameters are usually provided and are a function of the surface area and heat transfer characteristics of the cooling process / material. It is important that the cooler deliver the coolant at the proper flow and pressure. If the flow or pressure is too low, lack of heat. If the flow or pressure is too high may cause damage to the equipment.

Condenser heat dissipation Your choice includes air-cooled coolers that emit heat to the surroundings or a water-cooled cooler that distributes heat to the water supply.

The freezer provides heat removal for a variety of processes and equipment. When appropriate size and selection, the cooler increases production speed and accuracy, protects valuable process equipment, and reduces water consumption and associated costs. If the size is too small, the cooler will not cool normally; if it is oversized, it will be invalid due to excessive cycling. In addition to having sufficient cooling capacity, the cooler must deliver the cooling fluid at the appropriate pressure and flow rate.
