Features
The 400 CHU has the power to heat small to medium sized structures, thaw over 6,000 sq ft of frozen ground or cure concrete slabs up to 14,000 sq ft.
• Gas versions operate on LP or NG while Tri-fuel versions operate on diesel, LP or NG.
• The compact size and bi-directional fork pockets make the 400 CHU easy to place on even the smallest job sites.
• System operation is controlled and monitored from the central heating module control panel.
• 7 LED lights indicate operation of all essential systems for easy monitoring and troubleshooting.
• Fluid circulation system is low pressure and atmospherically vented. There is no chance of an explosion or line burst due to pressure build-up. No special boiler certification is required to
operate unit.
• A “rapid air elimination” feature ensures quick setup-and-go operation.
• Modular design allows the unit to conform to most special job requirements.
Combine the 400 CHU with DryAir accessories for specialty heating projects:
D-CAN 30 Desiccant Dehumidifier: Dry out flooded structures or control humidity in buildings under construction to speed drying time of paint, mortar, specialty coatings or drywall compound.
Plate Heat Exchanger: Temporarily tie in to boiler systems while the permanent water heater is being replaced or down for maintenance.
HEFA 250EX Explosion Proof Exchanger: 250,000 BTUs of explosion proof space heating for oil and gas sites or industrial/mining applications where there is a risk of combustion from airborne gases or particles in the space.
Hose Reel and Thawing/Curing Hose: Wrap pipelines or fluid vessels to provide freeze protection.
