Welltech Cooling Towers produces a broad range of condenser coils for HVAC&R applications, specifically designed to our customers’ exact specifications.We refrigerant condenser coils are suitable for use in a wide variety of HVAC air conditioning (condensing) and heat recovery applications. Condensor Coil Heat Exchangers are designed for the high pressure and temperature associated with refrigeration condensing. To ensure product durability under thermal expansion and vibration, the coils are designed with stronger brazed joints.Fin spacing and surface, tube pitch, circuiting and design can be varied to assure best performance while maintaining air and tube-side pressure-drop limitations.Copper, Aluminum, and S.S fins with S.S and Copper tubes are available for condenser coils to match the operating conditions and level of corrosion resistance needed for your application. Our application engineers will assist you in matching existing coil construction and dimensions to create the “perfect fit” for your replacement coil project.Welltech Cooling Towers in-depth understanding of the condensing process includes desuperheater, condenser and subcooler phases, uniquely combined to optimise system performance and efficiency.
Air cooled – If the Condenser Coil Heat Exchangers is located on the outside of the unit, the air cooled condenser can provide the easiest arrangement. These types of condensers eject heat to the outdoors and are simple to install.
Most common uses for this condenser are domestic refrigerators, upright freezers and in residential packaged air conditioning units. A great feature of the air cooled condenser is they are very easy to clean. Since dirt can cause serious issues with the condensers performance, it is highly recommended that these be kept clear of dirt.
Water cooled – Although a little pricier to install, these condensers are the more efficient type. Commonly used for swimming pools and condensers piped for city water flow, these condensers require regular service and maintenance.
They also require a cooling tower to conserve water. To prevent corrosion and the forming of algae, water cooled condensers require a constant supply of makeup water along with water treatment.
Depending on the application you can choose from tube in tube, shell and coil or shell and tube condensers. All are essentially made to produce the same outcome, but each in a different way.
Evaporative – While these remain the least popular choice, they are used when either water supply is inadequate to operate water cooled condenser or condensation temperature is lower that can achieved by air cooled condenser. Evaporative condensers can be used inside or outside of a building and under typical conditions, operate at a low condensing temperature.
