Heat Kits

This category features commercial and industrial-grade electric heat kits—also known as supplemental or emergency electric heat strips—engineered for field or factory installation within compatible air handlers, modular blowers, and packaged rooftop units (RTUs). These heavy-duty open-wire or sheathed heating element assemblies are utilized to provide primary electric resistance heating, multi-stage auxiliary heating, or critical frost protection during low-ambient heat pump defrost cycles. Constructed with premium nickel-chromium (NiCr) resistance wires supported by high-dielectric ceramic insulators, these kits incorporate integrated heavy-duty sequencers, thermal limit safety switches, and built-in circuit breakers or fuses to prevent overcurrent and thermal runaway. This comprehensive range provides HVAC contractors, mechanical installers, and facility engineers with code-compliant, UL-listed solutions engineered to add targeted, high-capacity heating elements to ducted forced-air networks.
