USED NDI/APOLLO 44 CONTROLLER FOR SALE AT $26

 

 

 

 

The Now Devices Inc. (NDI) Apollo 44 is a basic ON/OFF differential temperature controller from the early 1980s for use with closed loop and drain back systems. This controller has a single 120 VAC output that is hardwired directly to the circulation pump. The output relay is rated at 1 HP at 120 or 240 VAC. The controller incorporates a solid state operational amplifier to determine when the pump should be turned ON and OFF. Two 30 K ohm sensors, one for the storage and one for the collector are required for the NDI/Apollo 44.

 

The ON and OFF Delta Ts are easily adjusted as are Freeze and Over-Temperature protection. Click here for a copy of the NDI/Apollo 44 Installation & Installation Manual.

 

If you are looking to replace your defective NDI/Apollo 44 controller or just want one as a backup, order this one today as it is the only one left. Prices shown do not include postage.  Colorado sales will be charged the appropriate sales tax.
