Makeup Air Unit System Energy Efficient Heater - Cambridge Air Solutions

Cambridge M-Series Make-Up Air Unit (MUA) for Commercial & Industrial Ventilation

Name: M-Series Make-Up Air System
Brand: Cambridge Air Solutions

Industrial ventilation designed for energy and operational cost savings.

The Cambridge M-Series System is a commercial and industrial make-up air unit (MUA) designed to provide reliable, tempered outdoor air while supporting energy efficiency and lower installation and maintenance costs. The M-Series make-up air system is designed for facilities that need to replace air exhausted from the building while maintaining appropriate indoor temperatures and ventilation.

M-Series heaters feature patented Cambridge Low-Fire Start Technology and proprietary stainless-steel burners designed to provide year-round make-up air ventilation and tempered outdoor air for demanding commercial and industrial applications.

The Cambridge MUA can be used for new construction, plant expansions, renovations, HVAC upgrades, and industrial retrofit projects.

A Cambridge make-up air unit is also available with Variable Frequency Drive (VFD) control to respond to changing airflow requirements and help reduce operating costs. Optional cooling coils are also available for applications requiring both heating and cooling.

What Is a Make-Up Air Unit?

A make-up air unit (MUA) is an HVAC system designed to replace air that has been exhausted from a building. When exhaust fans, process equipment, or other ventilation systems remove air from a facility, that air must be replaced to maintain proper building pressure and ventilation.

A make-up air system draws outdoor air into the building and tempers it before distributing it into the facility. Depending on the application, a make-up air unit may heat, cool, filter, or otherwise condition the incoming air.

For commercial and industrial facilities, make up air ventilation can help:
•Replace air removed by exhaust systems
•Support proper building pressure
•Provide required outdoor ventilation air
•Temper incoming outdoor air
•Improve indoor environmental conditions
•Support industrial processes that require significant exhaust
•Reduce the impact of cold outdoor air entering through uncontrolled openings

Cambridge M-Series Features

From the factory, Cambridge Make-Up Air Units include components designed to support reliable operation, long equipment life, and energy savings. The M-Series can be configured to meet the airflow and heating requirements of a wide range of demanding commercial and industrial make-up air applications.
• Patented Low-Fire Start Technology to increase reliability and save energy
• Proprietary stainless-steel burners
• 100% Combustion Efficiency
• Up to 6,500 MBH Capacity
• Up to 75,000 CFM
• Natural Gas or Propane

Longevity and Safety
• Shielded and ventilated motor assembly
• Low voltage hot surface igniter
• Closed cell, non-water absorbing insulation in the base to help eliminate condensation issues
• High-temperature limit switch, airflow switch and gas modulation control

Facility Fit
The Cambridge M-Series is available with configuration options designed to accommodate different building layouts, airflow requirements, and environmental conditions.

• Several cooling options – including DX or chilled water coils and evaporative cooling
• Motorized inlet or discharge damper
• Single or dual rain hood inlet options, V-Bank filter sections & high-efficiency filters
• Multiple discharge options

Energy-Efficient Make Up Air with Low-Fire Start Technology
One of the distinguishing features of the Cambridge M-Series is patented Low-Fire Start Technology. The technology is designed to help improve reliability and energy performance during unit startup by allowing the system to begin operation at low fire before increasing output as needed.

For facilities operating large air make up heaters, controlling heating output according to actual demand can help reduce unnecessary energy consumption while providing the tempered outdoor air needed by the building.

When Should You Consider a Cambridge M-Series Make-Up Air System?
The M-Series may be appropriate when a facility:
• Has substantial process or building exhaust
• Needs to replace large volumes of exhausted air
• Experiences negative building pressure
• Needs to temper incoming outdoor air
• Requires reliable commercial or industrial ventilation
• Is upgrading an existing HVAC system
• Is building a new facility or renovating an existing building for a retrofit
• Requires heating and/or cooling of air

M-Series Heating and Cooling Options
Although make-up air is often associated with heating outdoor air during cold weather, some facilities require year-round temperature control.

The Cambridge M-Series can be configured with optional cooling equipment, including:
· DX cooling coils
· Chilled-water coils
· Evaporative cooling

This allows the M-Series to provide year-round make-up air for applications where outdoor air needs to be tempered during both heating and cooling seasons.

Choosing the right air make up system depends on your facility's airflow requirements, exhaust system, heating and cooling needs, building configuration, and operating conditions. Cambridge Air Solutions and its local representatives can help determine the appropriate M-Series configuration for your application.
