Heat Exchanger Coil
Our extensive product portfolio of coils offers a wide range of customization options, including varying tube diameters, tube patterns, fin profiles, materials, and features, allowing us to tailor our coils to meet the specific requirements of any application and fluid type. This includes condensers, evaporators, water coils, and steam coils for HVAC and industrial applications.
Telawell heat exchanger coils are manufactured with a variety of tubling material options, including copper and stainless steel. Additionally, we offer tube diameter options of 3/8, 1/2, and 5/8 inches, as well as fin material options of aluminium, copper, and stainless steel.
To achieve customized fin spacing, we use collars that also facilitate contact between the fin block and the tubes. Furthermore, our mechanical expansion of the tubes ensures a perfect bond between the fins and the tubes, resulting in maximum heat transfer between both fluids.

Our stainless steel evaporator coils offer superior performance and durability, making them ideal for various applications. Constructed from high-quality stainless steel tubes, they provide excellent corrosion resistance and thermal conductivity.
Water coils are specialized heat exchangers that utilize water for efficient heat transfer. They consist of tubes with circulating water, augmented by fins that increase the heat exchange surface area.
Steam coils are high-performance heat exchangers that transfer heat from steam to a secondary fluid, typically air or water. Comprising a series of tubes through which steam flows, they efficiently convey heat to the surrounding fluid, raising its temperature.
The Direct Expansion (DX) coil is a key component in modern air conditioning and refrigeration systems, utilizing a direct expansion refrigeration cycle for efficient heat transfer. Refrigerant evaporates directly within the coil, enabling optimal heat exchange.
The primary function of a booster coil is to augment the temperature of the air circulating within a duct system. This is accomplished through the reheating of the air using hot water, typically ranging from 140°F to 200°F, thereby elevating the air temperature to the desired level.
A reheat coil receives warm water or steam from a central boiler, and as air flows over the coil, it absorbs heat, precisely controlling temperature before redistribution to the designated zone, thereby optimizing energy usage in specific applications.
Chilled water coils, a type of heat exchanger, cool and dehumidify air in HVAC systems by transferring heat from the air to the chilled water, resulting in cooled and dehumidified air.
Refrigeration coils are essential components in HVAC systems, facilitating efficient heat transfer and precise temperature control in air conditioners, heat pumps, and other applications.
A fan coil unit (FCU) is a simple, cost-effective HVAC solution that provides heating and cooling. It’s energy-efficient, quiet, and flexible, making it ideal for various applications.
Terminal units control airflow from a central air handler to an occupied space, regulating primary air volume to maintain thermal comfort. They adjust airflow based on real-time temperature measurements to achieve and maintain the desired temperature.
Blower coil units (BCUs) efficiently control temperature and improve indoor air quality in commercial applications. They provide optimal comfort for occupants and are essential in modern heating and cooling systems.
Condensing units are the heart of refrigeration systems, efficiently converting refrigerant from gas to liquid to facilitate cooling. This guide explores their workings, types, applications, and importance in modern refrigeration systems.
A frame coils optimize heat transfer surface area while staying compact. The “A” shape design enhances airflow and efficiency, making them ideal for evaporator coils in air conditioning systems where maximizing cooling performance is key.
Steam distributing coils, or ‘no-freeze coils,’ prevent freezing in low temperatures. An inner tube within an outer tube allows steam to condense, ensuring a consistent flow of warm condensate and preventing cold spots.
Desaturation coils are essential HVAC components that reduce humidity in air handling units. This enhances comfort, improves energy efficiency, and works synergistically with other cooling systems.
A run-around coil system recovers heat energy from exhaust air streams, often used in buildings where exhaust air contains harmful substances.
