Evaporator TEFCOLD 14289

An evaporator removes heat from a refrigerated space by allowing liquid refrigerant to boil inside finned coils. The refrigerant absorbs heat as it changes from liquid to vapour, lowering the temperature of the air that passes over the coils. This cooled air is then circulated back into the cabinet or cold room, maintaining the required storage temperature for food, drinks or other perishable goods.

The operator connects the evaporator to the refrigeration circuit, ensuring the refrigerant supply and return lines are correctly attached. Once the system is charged and powered, the refrigerant flows into the evaporator, where it expands and evaporates, drawing heat from the surrounding air. A fan mounted behind the coils forces air across the fins, accelerating the heat exchange. The vapourised refrigerant returns to the compressor to begin the cycle again, while the cooled air is distributed through the space.

These TEFCOLD evaporators are designed for integration into refrigeration systems, where they replace heat with cold air in a continuous loop. The construction includes finned coils that maximise surface area for efficient heat absorption, and a fan that ensures even air distribution. The units are mounted inside the refrigerated space, typically on a wall or ceiling, to maintain consistent temperatures.

Cleaning involves removing dust and debris from the fins and fan blades to maintain airflow and heat exchange efficiency. The coils should be inspected periodically for frost build-up, which can be defrosted either manually or through an automated programme if the system includes one. Regular maintenance ensures the evaporator continues to operate at peak performance, preventing temperature fluctuations in the refrigerated space.

The DB200H-I, DB200S-I and BA26SS models are variants within the TEFCOLD evaporator range, each suited to different refrigeration applications and system configurations.
