Specialty Products

HTPG provides a variety of specialty commercial refrigeration products including air handlers, demand defrost evaporator controls, and custom coils.

HTPG’s Air Handlers are an industrial grade product with heavy gauge mill-galvanized steel framing and sheet metal throughout. Designed specifically for the HVAC industry with a full range of options and accessories, these units are ideal for custom or design-and-build projects in refrigeration or air conditioning.

The Surveillant Demand Defrost Evaporator Controller reduces the energy used by the evaporator coil in refrigeration systems through precise control of superheat, fan management, and demand defrosts. It uses proprietary advanced algorithms to maximize energy efficiency while minimizing the effects of defrost on the space temperature resulting in energy savings, constant product temperature, and reduced product shrinkage.

HTPG’s experience in coil manufacturing, materials, fin spacing, tube diameter, and circuiting are unmatched in the industry. Whether for OEM, replacement or retrofit customers, HTPG’s Lean manufacturing featuring one piece flow is ideally suited to meet your unique coil requirements. We offer everything from expert design services to full production capabilities.
