Spacepak 45ac-wpak-120-cl 4 Row Hydronic Heating Coil

Product Description

The SPACEPAK 45ac-wpak-120-cl is a 4-row hydronic heating coil designed to mount directly to horizontal and vertical fan coil units. Constructed with a galvanized steel casing, aluminum fins, and 3/8-inch copper tubing, this hot water coil delivers consistent hydronic heat transfer in residential and light commercial air handler applications. The unit features conveniently placed plugs for bleeding trapped air and purging water during maintenance or seasonal shutdowns. Licensed HVAC technicians and hydronic heating specialists handle installation and service of this coil.

This coil is designed for use with SpacePak 4860 series air handlers. It is rated for both horizontal and vertical installation, providing flexibility in equipment room layouts. The left-hand configuration suits specific duct and cabinet orientations common in forced-air hydronic systems. Sheet metal return air ducts can attach directly to the coil cabinet, and the removable return air panel allows assembly of flexible return air duct connections. This unit is manufactured in the USA and meets applicable Prop 65 requirements.

Key Features

• 4-row coil depth for efficient hot water heat exchange in hydronic systems
• Mounts in horizontal or vertical orientation to suit varied air handler installations
• Galvanized steel casing resists corrosion in mechanical room environments
• Aluminum fins promote heat transfer and reduce overall coil weight
• 3/8-inch tube sizing with 8-circuit configuration for balanced flow distribution
• Integrated purge plugs simplify air bleeding and system drainage during maintenance

Compatibility

Designed for direct mounting on SpacePak 4860 series horizontal and vertical fan coil air handlers as an OEM-style hot water heating coil.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified hydronic heating professional. Shut off the hot water supply and relieve system pressure before disconnecting or installing the coil. Purge air from the coil using the provided plugs before returning the system to service. Follow local mechanical codes and the equipment manufacturer instructions for hydronic coil connections and duct attachment.
