2,500,000 BTH/HR Make Up Air Heater, 230V, 1Ø, 50 Amp or 208V-230V, 3Ø 30 Amp 14,000 CFM

• Our makeup air system delivers forced mechanical ventilation to the project site, allowing treated air to circulate throughout it.
• Our system raises the surface temperature of curing construction materials to speed up and optimize the curing process while still protecting quality
• Manage site humidity by providing treated air; we can control site humidity with pressurization to speed up cure periods and limit the risk of mold.

FEATURES
• Prototype & Production Tested Design
• Modulating burner design to right size the heater to any ambient condition
• Simple access for maintenance and operations
• Weatherproof enclosure - water tested to UL/CSA/ANSI standards.
• Safety guards for all electrical connections
• Designed to be switchable between natural gas and propane gas with minimal changes with valve orifice
• Advanced burner management controller monitors all aspects of heater operation
• Simple user interface and operation
• PID Control with robust algorithm for temperature control to reduce fuel consumption and protect heater
• Highly reliable outlet air temperature sensor
• Tool-less latches standard with key or external lock optional
• All parts powder coated, galvanized or aluminum
• Highly portable design with fork pockets in both directions and a four point lifting system.
•  Easy access control panel with clear labelling to support field operations

Features

• Variable controller technology adjusts to the ambient temperature to provide consistent heat to the project while reducing fuel use.
• Designed for reliability: We design for continual uptime since heating equipment must be ready to function in any scenario, from freezing weather to other challenging conditions.
• Stainless Burner Head: Our modulating burner head allows you complete control. However, let's face it: the ambient temperature changes frequently, and the system must be prepared to respond.

Benefits

• Our makeup air system delivers forced mechanical ventilation to the project site, allowing treated air to circulate throughout it.
• Our system raises the surface temperature of curing construction materials to speed up and optimize the curing process while still protecting quality
• Manage site humidity by providing treated air; we can control site humidity with pressurization to speed up cure periods and limit the risk of mold.
