Overview

Cambridge offers a NEW line of competitively priced Make-Up Air Systems with many unique features that provide easier installation, quicker start-up and longer life. The M-Series is designed to provide year round ventilation and tempered make-up air for a wide variety of demanding commercial and industrial applications. It is also available with Variable Frequency Drive (VFD) control to respond to varying air needs in order to reduce operating costs. DX or chilled water coils and evaporative cooling options can also be specified.

DRAW-THRU MAKE-UP AIR HEATER

• Natural Gas, LP Gas or Propane Air Burners

COST EFFECTIVE WAY TO PROVIDE FRESH, TEMPERED MAKE-UP AIR FOR:

• Restaurants and Commercial Kitchens
• Gymnasiums and Indoor Sports Facilities
• Automobile Service and Repair Facilities
• Wastewater and Sewage Treatment Facilities
• Manufacturing and Assembly Plants
• Parking Garages
• Foundries
• Paint Booths

Direct gas-fired technology is the most energy efficient choice for heating make-up air because it does not use a flue or heat exchanger. The gas is burned directly in the air stream being heated. That means 100% of the available heat (every BTU of gas burned) is then delivered directly and efficiently to the building.

Indirect gas-fired make-up air heating equipment is only 60% to 80% efficient due to heat exchanger inefficiency and heat lost up the flue. It is also possible to experience condensation within heat exchanger sections of indirect-fired units in cold climates causing corrosion and premature failure.

Do not substitute any type of indirect gas-fired make-up air heater for a Cambridge M-Series direct gas-fired heater. The technologies are different. Performance will be jeopardized and energy costs will increase.
