You are purchasing one 50k BTU unit heater . Perfect for garages, shops, greenhouses etc. They can also be hooked up to a “cold/chilled” water source to provide cool air as well! Can be mounted or set on shelf, bench, or floor.

Ports on the side as they should be, so you don’t have clearance issues if you want to hang them up close to the ceiling. Also, if you plumb the port closest to the fan as your hot supply, this will allow you to preheat and then super-heat the air as it passes through the water coil. We do not use a rheostat as these fan motors are not made for that application and can burn out your motor quickly.

There are TWO yes two warranties

Manufactures warranty: MFG defects – does not include freezing, rust, or corrosion leaks – shipping not included in warranty

Customer abuse warranty: If you freeze the unit, you can buy a replacement coil at a discounted rate -shipping not included in warranty

Unit Heater

  • 9 ft. power cord plus 1 ft cord w/plus delivers optimal, safe AC power through a 14-Gauge heavy-duty cord (this allows you to choose if you want to use the 2 speed switch or just hard-wire on one speed.
  • replaceable 12×12 water to air coil inside
  • 2 speed capable or direct wire up one of the speeds if you don’t want to use the switch
  • US standard 1″ copper connections
  • Includes holes in top and bottom housing for bolts AS WELL AS mounting holes for for threaded rod for ease of installation (actual mounting rods and hardware NOT included)
  • Dimensions 15 3/4″ X 12″ X 13 1/2″ (LxWxD (including fan shroud)
  • Weight in box 27#

Sidearm Heat Exchangers

Sidearm heat exchangers are designed with natural thermo-siphon concept on domestic hot water side.  Traditional sidearms are made of two bare copper tubes.  Thus its capacity is decided by the length of sidearm-tubes and the heat transfer efficiency is very low.  The stainless steel fin-enhanced sidearm increases heat transfer efficiency significantly by using finned tube internally, which has surface area five to eight times bigger then bare tube and produces great turbulence on system side.  With a fin-enhanced sidearm you need only a shorter unit, but get bigger capacity and faster heating.

Heat exchangers are used to exchange heat between two fluids.  Plate Exchangers are high performance components and provide a high level of efficiency combined with compact dimensions and low weight.  The special moulding of the plates produces the turbulent flow necessary for effective heat transfer.
