Control Dampers

  • Commercial Control Dampers

    • Commercial control dampers regulate the flow of air in an HVAC system. Intake, exhaust, or mixed air are typical applications. These control dampers meet the requirements of ASHRAE, California Title 24, and IECC.

  • Insulated Thermally Broken Control Dampers

    • The ICD series are used in applications where it is necessary to minimize the thermal transfer of energy and reduce condensation​

    • Minimizes the transfer of thermal energy and reduces condensation.

  • Face and Bypass Control Dampers

    • Two dampers connected together that allows one to open and one to close. 

    • Face and bypass dampers are used in applications where two dampers are connected together allowing one damper to open while the other damper closes.

Air Measuring Products

Airflow measuring products help buildings meet the minimum outdoor air requirements of ASHRAE Standard 62.1 or California Title 24 by providing accurate monitoring and control of outside air.
Differential pressure based airflow measuring products use an array of air pressure pick-ups to compare the total pressure going through the airflow station with the static pressure in the station.
Thermal dispersion technology utilizes an array of thermal dispersion nodes positioned across the face of a duct or opening. Each node contains a pair of precision matched thermistors. One thermistor measures the ambient air temperature and the other is heated to a preset temperature differential above ambient. Each node measures air velocity. These use the known relationship between heat transfer and air velocity along with measuring power consumption needed to maintain the fixed temperature difference between the thermistors.

Energy Recovery Ventilators

Energy recovery ventilators (ERV) provide pre-conditioned fresh outdoor air to meet ASHRAE Standard 62 ventilation rates using recovered energy from the exhaust air stream. The benefits include improved indoor humidity levels, reduced energy costs and lower first cost for air conditioning (due to a reduction in outdoor air load). All product designs emphasize the need for low maintenance and economical first cost.

Effinity™ with Building Management System Integration (PTC/BTC)

High-Efficiency Commercial Gas-Fired Unit Heater

Operating at up to 97% thermal efficiency, Modine’s Effinity™ condensing unit heater features the highest efficiency available in North America for commercial and industrial gas-fired unit heaters, which will dramatically lower energy costs and CO2 emissions. This industry-leading efficiency is a result of the coupling of our secondary heat exchanger technology with our robust tubular primary heat exchanger design.

The Effinity™ guards against mold and maintains uniform wall-to-wall temperatures with consistent air circulation.

All units are equipped with Building Management System (BMS) integration capabilities, allowing them to be added to existing BMS easily.

High-Intensity Infrared Heater

Modine’s high-intensity ceramic infrared heater is approved for indoor unvented installation. It does not utilize a fan, thus eliminating noise and draft distractions. Gas and power connections are simple, and maintenance is inexpensive since there are no moving parts to maintain.

Ideal for use in manufacturing facilities, vehicle repair centers, warehouses, or loading docks. Also perfect for indoor sports spaces like indoor tennis courts or golf driving ranges.

Lodronic™ Low-Temperature Hydronic Heater (HCH)

Unlike other hydronic unit heaters on the market the Lodronic™ low-temperature hot water unit heater was designed and engineered specifically for use with high-efficiency boilers.

The typical oversized hydronic unit heater overworks the high-efficiency boiler system resulting in poor system performance and lower temperature output.

By using the Lodronic™ hydronic unit heater with the high-efficiency boiler system, there will be a significant performance improvement when compared to standard hydronic unit heaters.

Hazardous-Location Electric Heater 15kW, 480V AC, 3-Phase

Hazardous-location portable electric heaters have permanently sealed parts to prevent sparking while heating potentially hazardous locations. They can be used where flammable gases, vapors, powdered metals, or dust is present. These heaters are mounted on a lightweight aluminum portable cart so they can be moved wherever extra heat is needed. They are factory wired for direct plug-in and have a cast aluminum Killark male/female connection. These heaters come with a built-in thermostat.

Electric Plenum Heater, 5kW, 208/240V AC, 1Phase, Air Temp. Rise 57 F, Air Flow 275 CFM

General purpose electric plenum heaters can be installed for free-air discharge or with a duct system to supplement central heating. They heat hard-to-access or concealed areas, such as between a finished and drop ceiling, a plenum space, or other space where there is limited room. The heaters can be rotated on their axis, but they must be suspended horizontally and independently supported. They cannot be mounted vertically.

Electric Wall & Ceiling Unit Heater, 50kW, 480V AC, 3-Phase

Suspended electric wall and ceiling unit heaters suspend from a bracket or threaded rod for use in downflow or horizontal applications and save limited floorspace. They provide primary or supplementary heating in large or exposed areas like factories, warehouses, and stock rooms. They use a forced air system that heats the air using a heating element and a fan.
