DryAir 650 GTS
The DryAir 650 GTS GreenThaw system combines a diesel-fired hydronic heater, powered hose reel and circulation equipment in an enclosed trailer. Its burner is rated at 620,200 BTU/h input, with 5,000 feet of onboard hose. The flow-reversing controller helps distribute heat through ground-thaw and concrete-curing loops. Published standard coverage is up to 7,500 square feet for thawing or 10,000 square feet for curing at the manufacturer’s specified hose spacing; larger areas require added hose and accessories.
