Kooltronics - Heat Exchanger
The KOOLTRONIC standard line of Heat Exchangers is one of the most versatile available. It satisfies a broad range of application requirements by utilizing various heat transfer technologies. Heat Exchangers provide many of the advantages of Air Conditioners, and are generally less costly to install and operate.
KOOLTRONIC high performance Heat Exchangers combine powerful forced convection cooling with the advantages of a closed-loop cooling system, for environments that pose contaminant problems. The closed-loop design cools and recirculates the same clean air, isolating components from the hostile environment.
Air-to-Air Heat Exchangers are the ideal choice for applications that can tolerate operating temperatures somewhat higher than ambient. The KTHE Series features a refrigerant-charged fin-and-tube coil, employing the heat pipe principle. The KXHE, KXNP, KNXH and KWHE/KWHX Series utilize a high-efficiency convoluted aluminum heat transfer element. These elements provide excellent thermal transfer performance and are easily removed for cleaning. KOOLTRONIC manufactures its own Heat Exchanger elements. All Kooltronic Heat Exchangers provide a large heat transfer area in a compact package with high performance air systems for high flow rates and thorough air distribution within the electronics electrical enclosure.
KPHE Water-to-Air Heat Exchangers fill the performance gap between Air-to-Air Heat Exchangers and Air Conditioners. Where a reliable, clean, cool water supply is available, they are often the ideal solution when extreme contaminant or temperature conditions are present.
The adaptability of KOOLTRONIC Heat Exchangers is increased by flexible mounting configurations (external, internal, vertical, horizontal) and a comprehensive line of accessories and options. All units are easily installed, with mounting flange gaskets attached, to provide a positive seal to the enclosure. The TrimLine KXNP Series units feature the exclusive M/TAB Mounting System and are interchangeable with TrimLine Air-Cooled or Water-Cooled Air Conditioners.
Most KOOLTRONIC Heat Exchangers are designed for installation in normal indoor atmospheres. For operation outdoors, weather protection and special protective features are required. The use of standard indoor units outdoors would invite damage and early component failure, and will invalidate the KOOLTRONIC warranty. The Intrepid Outdoor Series were specifically designed for outdoor applications. Integrity NEMA 4/4X Heat Exchangers are also available for outdoor installation or applications requiring washdown.
Each KOOLTRONIC Heat Exchanger is engineered for performance and built for reliability. All standard Air-to-Air Heat Exchangers are UL/CUL Listed and maintain the NEMA Enclosure Rating referred to in the individual Series sections, except the KTHE Series.
General Specifications for Heater Exchangers
PRECISION BALL-BEARING MOTORS: All blower motors are UL/CSA recognized and include automatic-reset thermal overload protection and double-sealed or double-shielded precision ball bearings. Special permanent lubricants perform over a broad temperature range: -200F (-290C) to 2500F (1210C). Consult KOOLTRONIC for motors designed to meet military or other extreme environmental specifications. Tube axial fans are rated to perform at 140F (-100C) to 1580F (700C) and are designed to meet UL, CSA,and VDE.
RUGGED CONSTRUCTION: Precision-engineered heavy gauge steel construction insures that Heat Exchangers will stand up under tough applications.* PERMANENT FILTERS: Designed to last the life of the unit, the filters included with all Heat Exchangers consist of a multi-layer grid of sturdy, corrugated aluminum in a one-piece aluminum frame. Filters must be kept free of accumulations, to prevent reduction or loss of performance and/or damage to equipment. Disposable filters are also available. Filters are not required on water-cooled models (KPHE Series).
BAKED EPOXY FINISH: Durable, baked-on gray epoxy finish is standard. Other finishes are available.* POWER: 115 VAC or 230 VAC, 50/60Hz is standard. For other voltages and frequencies or other special requirements, consult KOOLTRONIC.*
POWER CORD: All 115VAC models are supplied with type SJT three-wire cord with plug. 230VAC units have three-wire cords without plugs for direct wiring to power source. Lengths are shown in the Series sections. Special lengths and/or plugs are available.
