36PHR

 

MODEL SIZES 30kW - 36kW

 

Fitted with a thermometer to indicate the outlet temperature, which enables flow rates to be adjusted when heaters are either fitted with a by-pass, branched off a much larger flow pipe, are used in multiples or are operated in parallel with an alternative means of heating.

 

Circuit breakers are fitted instead of the On/Off switch and protect the heavy power circuits against short circuit. These not only act as the main switch, but in the event of a water temperature rise within the heater being sufficient to operate the safety thermostat, a trip is triggered within the breaker such that the heater is totally isolated at its point of supply.
The unit will not operate again until both the safety thermostat and the breakers are manually reset. Operation of the of the safety thermostat switches off the working contactors before energising the in-built shunt trip of the breaker, giving the unique Thermalec double protection against overheating and damage to the elements. 

Standard Specification

 

HEATER BODY:
Cast in BS-EN-1561-1997-ENGJL-200 iron, with a heavy fusion bonded epoxy coating impervious to chemically treated pool water, constructed in accordance with British Patent 2.092,282 Design pressure of 35psi (2.46kg/cm2) with 3/4" safety valve(s) set to operate at the maximum normal working pressure of 30psi (2.1kg/cm2) giving protection to both the heater and and the installation as a whole against over pressure. A 1/2" drain valve at the lowest point allows the heater to be left empty in winter. Flow connections consist of easily removable uPVC stub flanges into which the pipes may be fitted using suitable adhesive, as the flanges can be released easily from the heater no unions are required, nor is any form of heat sink needed. Flow direction is from left to right, but may be reversed quite simply on site following the installation instructions.

HEATER ELEMENTS:
Heavy duty incoloy sheathed elements to BS-EN-60335-1, with low Watt density for long life, are mounted individually in a removable top plate, which allows complete inspection of the interior of the vessel.  

CONTROLS:

Heavy duty contactors control the power supply to the elements. The contactors are switched in turn by a filter pump interlock relay, a pool temperature controller with less than 1°C differential, and a manual reset safety thermostat to operate before the temperature reaches 53°C. The control circuit is protected by a 2A fuse. A minimum of 6 indicator lights monitor every stage for simple diagnostic servicing. The controls are mounted in a plastic coated steel enclosure above the heater body. Cable entry is through a removable plate in the rear panel.
