Evaporator coils, also known as DX coils, are used to cool or remove moisture from air streams. As one of the four main components in a refrigeration or air-conditioning cycle, the evaporator coil removes heat and moisture from the indoor air that flows over it. Because stainless steel is resistant to corrosion, it is a good choice for evaporator coils in harsh environments.
Emergent Coils provides evaporator coils to meet your exact specifications, often at a fraction of the cost of a new coil from the original equipment manufacturer (OEM). Our coils come with a variety of tube, fin and material options.
While HVAC coils with copper tubes and aluminum fins are our most popular items, we may recommend other materials based on your specific situation. Stainless steel evaporator coils are resistant to corrosion and durable, making them a wise choice for corrosive surroundings. Stainless steel also has high tensile strength. Because stainless steel does not transfer heat as efficiently as aluminum, stainless steel tubes with aluminum fins are an option to increase heat efficiently transfer at a lower cost.
Stainless steel reduces the possibility of leaks in evaporator coils because it is resistant to corrosion. Since salt is corrosive, buildings located near the sea or other salty locations will benefit from stainless steel evaporator coils. Many industries will also benefit from stainless steel evaporator coils, including chemical, food & beverage, oil & gas, and pharmaceutical.
Emergent Coils offers online tools to help with sizing and ordering evaporator coils. Watch our video demonstrating how to measure an evaporator coil and use the blank drawings we provide to record the measurements.

Chilled water coils can get clogged with dirt, dust or other pollutants, causing a normally cool building to heat up during the summer months. In chilled water systems, the chiller unit is often installed behind the building or on the roof. Most chilled water coils have air entering the system at a temperature between 75°F to 95°F, and chilled water at a temperature of approximately 45°F. Chilled water coils typically run between 3 and 10 rows deeps to handle the extreme difference between the air and chilled water temperatures. The chilled water coil is usually made of copper tubing with aluminum fins, bent into an S shape, to increase the heat transfer area. Since chilled water coils become clogged relatively frequently, they need to be replaced quickly to keep the chilled water system running smoothly. Emergent Coils offers a wide variety of standard and custom chilled water coils to keep your building cool when the weather outside is too hot to handle.

Stainless steel may not be the most common choice of materials for chilled water coils, but it has advantages over other materials in many situations. When you think of harsh or corrosive settings, stainless steel should be considered because it is resistant to corrosion.
Chilled water coils are used in a wide variety of HVAC systems, including air cooling and dehumidifying. As I’ve mentioned before, chilled water coils with copper tubes and aluminum fins are our most popular items. Copper is most commonly used for tubes because it transfers heat efficiently. Fins require more material, and aluminum is often used because it transfers heat efficiently at a lower cost. Both copper and aluminum can corrode in harsh environments, making stainless steel a better choice where leaks caused by corrosion can be hazardous.
Stainless steel chilled water coils are also durable and have high tensile strength. Stainless steel is a smart choice for manufacturing facilities in the chemical, food & beverage, oil & gas, and pharmaceutical industries. In addition, because salt is corrosive, having chilled water coils made of stainless steel in areas near the ocean makes sense.

If you need help with sizing your chilled water coils, we have a sizing video on our website along with blank drawings you can use to record the measurements. If you need help, give our coil specialists a call at 1-855-Coil-Now or email us at email@example.com today.

Water coil trivia can come in handy when you run out of sports trivia over beers with your HVAC buddies. Here are some water coil factoids to impress your friends: • Water-tube boilers date back almost 2,000 years. • Chilled water has been the primary medium for heat transfer from building coils to refrigeration systems since the beginning of modern HVAC design. • The first modern water-tube boiler was invented by William Blakely in 1796 • A hot water coil and chilled water coil are often viewed as completely different, but a water coil is equally capable of handling hot and chilled water. • Chilled water coils are often used for comfort cooling, dehumidifying, heat reclamation and process cooling. • Hot water coils are often used for booster heating, comfort heating, fluid process heat, preheating, reheating, and waste heat reclamation. • The construction of hot water coils and chilled water coils is similar, including tube diameter, fin design and wall thickness. • A hot water coil typically has one or two rows, while a chilled water coil has three or more rows. • Fluid pressure drop and fluid velocity are critical to the operation and longevity of water coils. Give us a call if we can help with your water coil needs. Cheers!
