GM76 – Compact Direct Fired Heater

Modular Make-Up Air Systems

For More Information:

GreaseMaster - GM76

The Direct Gas Fired Make-Up Air package is designed to deliver tempered make-up air for installations requiring frequent air changes. Units are designed for natural and propane gas applications, and for indoor or outdoor installation.

Direct Gas-Fired Heater, for use in tempering make-up air. Packages are certified to the ANSI Z83.4-Second Edition and CSA 3.7-2006 combined safety standards. One size is available with a max BTU rate of 241,290 and 1,800 CFM. Units are designed for natural or propane applications and are rated for indoor/outdoor installations in commercial occupancies. A unique feature is the self-adjusting burner profile plates allowing 2-speed and variable-air-volume applications. The plates ensure proper air velocity and pressure drop across the burner for clean combustion. Spring-loaded profile plates react to the momentum of the fresh air stream, therefore, no motors or actuators are needed to drive them, nor do they need to be manually set to a specific position.

Standard features include intermittent spark ignition system with timed safety lockout, and redundant gas valves. Units consist of a galvanized enclosure with an elevated gas burner which burns directly in the air stream. The burner consists of non-clogging, stainless steel combustion baffles attached to a cast iron gas supply section. The burner is capable of nearly 100% thermal efficiency with a maximum turndown ratio of 15 to 1. The products of combustion mix with the make-up air which is introduced into the heater intake directly from outside the building. The burner module has a standard horizontal inlet and discharge duct connection and is located upstream of the blower. The heater has a standard horizontal inlet designed to accommodate an outside air inlet hood with standard 2” filter and screen.

To satisfy a variety of installation requirements, packages are available in a number of configurations which include additions of filtered intake with easy access door and a trunkline that is used to move the air intake away from the grease laden exhaust air. Screened intakes are used to stop debris from being pulled in to the heater. The screened intake attaches directly to the filtered intake or the trunkline. Combination packages that include both exhaust and supply fans mounted on a single roof curb are also available, please contact your sales representative for more information.

Modular Packaged Unit

Modular Make-Up Air Systems

For More Information:

GreaseMaster: Modular Packaged Unit

The Modular Packaged Unit (MPU) is designed to be a factory packaged air conditioning and heating unit for 100% Outdoor Air (OA) applications. Units are sized to operate between 360 to 600 cfm/ton of cooling, depending on climate.

The modular packaged cooling unit is optimized to work in conjunction with highly efficient make-up air delivery methods, such as perimeter supply plenums. The unit can either have a down or end discharge, and can be used with both electric and gas heat. All refrigerant is environmentally friendly R-410A and condensers have a minimum SEER rating of 14 for greater efficiency.

One benefit of this unit is the multiple cooling stages. Multiple cooling stages increase the efficiency by not using 100% of the cooling capacity when this is not needed, thus allowing lower energy usage. An internal make-up air cooling thermostat automatically energizes the first stage when cooling of the make-up air is required. The same thermostat has a built in adjustable differential to energize the second stage of cooling when required.

The condensers are top mounted on the make-up air unit to minimize roof space requirements, and are situated for optimal airflow and serviceability.

Features & Benefits

  • High Efficiency 14 SEER Condensers
  • Integral Cooling Staged Thermostat
  • Multiple Stage cooling for lower energy usage
  • Pre-Piped and Charged Refrigeration Circuits
  • Optimized for 100% OA for kitchen use
  • Cooling requires no additional roof footprint
  • Coils and Condensers sized to comfort cool make-up air
  • R-410A Environmentally Friendly Refrigerant
  • Thermal Expansion Valves and Filter/Dryer Kits
  • External Equalization Lines for Thermal Expansion Valves
  • Hard Start Relay Kits on the Condensers
  • Condenser Disconnect Switch
  • Vacuum Tested and Leak Checked Lineset/Coils
  • Condenser Transformer Prewired
  • Thermostat Prewired and Interlocked with Heater

GM-IBT – Modular Indirect-Fired Bent Tube Heater

Modular Make-Up Air Systems

For More Information:

GreaseMaster: GM-IBT - Modular Indirect-Fired Bent Tube Heater

The Modular Indirect Fired Bent Tube Heater is designed to deliver clean air into an indoor environment. Units are designed for indoor or outdoor installation, and can use either Natural or LP gas. The standard unit includes a blower module and the GM-IBT heater module that is approved in the United States and Canada. The unit is listed to the ANSI Z83.8-2006 and CSA 2.6-2006 standards. Each furnace has a 6:1 Turndown Ratio and a maximum Turndown of 28:1 for the entire unit, depending on total required BTU Capacity and number of furnaces in the unit.
Every unit is programmed to start in high fire mode to ensure consistent light-off and is equipped with an electronic, Vernier-type fully-modulating control system. The duct furnaces are all type-409 stainless steel, and certified by the American Gas Association and approved by the Canadian Gas Association. Each model utilizes a single modulating stage, and between zero and three additional ON/OFF stages depending on the required heat output. In addition, the speed of its power-vent blower on the single modulating furnace is varied as the gas flow changes, thereby maintaining a constant 80% combustion efficiency over the entire gas-firing range of the unit.
