Capabilities Overview
Coilmaster insulated cased coils provide a complete coil assembly designed to simplify installation and reduce field labor. Each unit incorporates the heating and or cooling coil into a factory-built insulated cabinet with integrated drain pan and duct connection features. This configuration allows contractors to install the coil with only piping and drain connections, minimizing the time and cost associated with field-built coil housings.
Coilmaster insulated cased coils include 0.5-inch non-foil-faced insulation within the cabinet to help maintain thermal efficiency and reduce condensation on exterior surfaces. The assembly also features a 3/4 inch MPT drain connection, sealed access panel connections to prevent air bypass, and one-inch duct flanges on both the entering and leaving air sides of the cabinet for direct connection to ductwork. Standard cabinet construction uses 16-gauge galvanized steel, with stainless steel available for applications requiring additional corrosion resistance. An airflow label located on the connection end helps ensure proper installation and system operation.
How Insulated Cased Coils Work
Coilmaster insulated cased coils operate by directing airflow through a sealed cabinet where the heating coil or cooling coil transfers energy to or from the air stream. The cabinet design maintains controlled airflow across the coil surface, helping improve heat transfer performance and system efficiency.
Air enters the cabinet through the duct connection and passes across the coil fins and tubes, where heating or cooling occurs. When configured as a heating coil, an insulated heating coil warms the air before it continues through the duct system. Internal insulation helps maintain thermal control within the cabinet while limiting heat loss and preventing condensation from forming on the exterior of the unit.
During the cooling operation, moisture condenses on the coil surface as warm air passes through the cabinet. Coilmaster insulated cased coils include a factory-installed drain pan and drain connection that collects condensate and directs it safely away from the system. The sealed cabinet design and pre-installed drain system help reduce installation errors and ensure reliable condensate management compared with field-built coil housings.
Key Benefits vs. Field-Built Coils
Coilmaster insulated cased coils provide a complete coil assembly that reduces the amount of field fabrication required during installation. Field-built housings require additional time for insulation, sealing, and drain pan fabrication.
Key advantages include:
- Reduced installation labor and faster project timelines
- Factory-installed insulation and cabinet sealing
- Integrated drain pan connections for condensate control
- Improved airflow management through a sealed cabinet design
- Consistent coil performance compared with field-built housings
These advantages help contractors complete installations faster while maintaining reliable coil performance.
Common Applications and Industries
Coilmaster insulated cased coils are used in a wide range of HVAC and industrial air handling applications. The factory-assembled design makes these coils well-suited for projects where installation time and system reliability are critical.
Typical applications include:
- Commercial HVAC systems in office buildings and campuses
- Industrial duct systems requiring integrated heating coil or cooling coil solutions
- Retrofit projects where equipment must be replaced quickly
- Mechanical rooms where insulation and airflow control are important
- Facilities operating under tight construction schedules
Industrial heating systems may also incorporate electric heaters, circulation heater equipment, or tubular heater technology using tubular heating elements to provide additional heating capacity where required.
Selection and Customization
Coilmaster insulated cased coils are engineered to match the airflow, heating, and cooling requirements of each system. Cabinet construction materials can be selected based on environmental conditions, with galvanized steel cabinets standard and stainless-steel options available for corrosive environments.
Customization options include cabinet dimensions, insulation thickness, drain pan configurations, and connection locations. Coilmaster works with engineers and contractors to ensure the insulated cased coil integrates properly into the HVAC system while maintaining reliable airflow and heat transfer performance. Our insulated cased coils provide a complete, ready-to-install solution that helps reduce field labor while delivering dependable heating and cooling performance.
