Airrex AHSC-18R 1.5 Ton Portable Heat Pump | 16,800 BTU Cooling & Heating
Airrex AHSC-18R — 16,800 BTU Portable Cooling & Heating in One System
The Airrex AHSC-18R is a 1.5-ton portable heat pump that delivers 16,800 BTU/h of both cooling and heating from a single self-contained unit. Built around a 4-way reversing valve, it switches from air conditioner to heater on demand — a true year-round climate solution for industrial sites, repair shops, server rooms, and outdoor events. Standard 115V power and four lockable casters make it easy to roll in and run anywhere.
Why Choose the AHSC-18R
Cooling & Heating in One
A 4-way reversing valve lets the AHSC-18R work as an air conditioner or a heater, delivering 16,800 BTU/h in either mode.
R-454B Low-GWP Refrigerant
Runs on R-454B, a modern low-global-warming-potential refrigerant that meets current efficiency and environmental standards.
Digital Controls & Timer
Digital controls with high/low fan speed and a programmable timer make daily operation simple and precise.
5-Gallon Tank, Auto Shut-Off
A 5-gallon condensate tank with automatic full-tank shut-off protects the unit; an optional condensate pump enables continuous drainage.
Washable Air Filters
Removable, washable aluminum and stainless-steel mesh filters on both sides; an optional HEPA filter kit is available.
Portable with Locking Casters
Four 4-inch swivel casters (two locking) and louver-type outlets let you place and aim conditioned air exactly where it is needed.
Safety Devices for Dependable Operation
The AHSC-18R is engineered for long-term reliability in demanding environments.
A thermostat protector for the compressor works alongside high- and low-pressure switches, a 3-minute compressor delay timer, and fan motor protection. The automatic full-tank shut-off and tank position detector guard against overflow, while the ETL listing and LCDI recessed power cord confirm the unit meets recognized electrical safety standards.
