Services
Double Wall Condenser Coils
Our double wall condenser coils transfer heat between refrigerant discharge vapor and potable water. The patented coaxial design features a double-wall tube that prevents fluid mixing during operation. These C-UL-US listed units handle 650 psig refrigerant pressure while maintaining 500 psig water-side integrity for safety-critical applications.
Ice Machine Coils
Designed for commercial ice production, these coils utilize a 'tube-in-tube' configuration with convoluted inner tubes. Available in eight standard sizes from 150 to 1800 lb-ice/day capacity, they maintain 650 psig refrigerant pressure while optimizing heat transfer efficiency through counterflow arrangement.
Vibration Absorbers
Stainless steel and brass vibration absorbers dampen compressor-induced vibrations in HVAC systems. Engineered with deep-pitch corrugations and high-tensile braiding, these units handle up to 650 psig pressure while providing 36-48 inch flexible lengths for easy installation in refrigerant lines.
Refrigerant Heat Exchangers
Turbo heat exchangers improve refrigeration system efficiency by transferring heat between high-pressure liquid and low-pressure vapor. UL-listed models handle 1/2 to 50 hp systems, enhancing capacity through 10F subcooling and 20F suction gas superheat while preventing frost formation on suction lines.
Custom Coil Solutions
Our engineering team develops tailored heat transfer solutions for specialized applications. From modified standard models to complete custom designs, we adapt coil dimensions, materials, and configurations to meet unique pressure, capacity, and spatial requirements across various industries.
