A comfortable work environment is critical to increase and to maintain high productivity. The Malnar BTR evaporator coil is engineered to provide a comfortable and draft-free work environment. The BTR coil is designed with narrow profile to fit into tight locations where either the width of the coil or the available headroom is a concern. The aluminum and fibreglass construction makes the BTR coil lighter for easier installations using less structural steel support than galvanized coils would require. 

The Malnar BTR works with natural circulation patterns to speed uniform cooling while conserving energy. The coil draws warm air up from underneath and cold air is distributed out the sides. Using natural convection, the air drops to the floor, forcing warmer air back to the coil. This allows the use of low-velocity, low-noise fans to provide proper air flow quietly and comfortably. 

Like all Malnar products, BTR coils are professionally-engineered and painstakingly constructed to the most demanding specifications.
