Clean coils

A twist-lock UVC emitter designed for side-access installations allows up to six units to be connected to slide into an air handler to destroy microbes with ultraviolet light. The unit's high output in moving and cold air prevents microbial growth and destroys microorganisms using ultraviolet light in the C range.

All in the wrapping

A resilient blanket-type insulation for ductwork is composed of glass fibers bonded with a thermosetting resin to control heat loss and condensation. Faced Duct Wrap Insulation allows ductwork to handle conditioned air from 35 F to 250 F while the unfaced version can handle up to 350 F. Available with foil scrim kraft or vinyl film vapor retardant facing, it includes a 2-in.-wide stapling and taping tab on one edge.

Venting fire

A domed automatic fire vent offers low-profile design with enhanced thermal insulation. The Lumivent provides daylight, energy efficiency and automatic fire venting. It is designed to open automatically to allow smoke, heat and gases to escape from a burning building. It is suitable for buildings with expanses of unobstructed space such as factories, warehouses, auditoriums and retail facilities.

Cooling performance

An airfoil profile blade design in diameters from 16 inches to 49 inches produces a combination of high air volume, low power consumption and low noise. Manufactured from injection-molded engineered thermoplastic or cast aluminum blades and pressure die-cast aluminum hubs, the Multi-Wing Z Series Fan is suitable for HVAC, industrial and engine-cooling applications.

Heat it up!

Large boiler modules offer higher part-load efficiency and lower standby losses. Flex-Heat systems are redundant — if one module shuts down, the remaining modules provide heat until the problem is corrected.
