ALS15 discharge hose
At the safety valve outlet of a solar thermal or heating system, it can get pretty hot at times. The RESOL ALS15 sees to it that no-one gets hurt and nothing gets soiled when that happens.
The robust, heat resistant EPDM hose fits all common ¾“ safety valve outlets, can be individually shortened and is easy and effortless to install.
LT20 air separator
A solar thermal system has to be vented regularly in order to function efficiently. The RESOL LT20 air separator, installed in the solar flow line, permanently separates the air from the heat transfer fluid.
With the air vent valve and the hose included, the collected air can be discharged manually.
VM1020 flowmeter
A correct flow rate is vital for the function of a solar thermal system. The RESOL VM1020 flowmeter indicates flow rates from 1 to 13 litres per minute, with the integrated flow rate limiter, the value can be throttled.
With the also integrated fill/drain valve, flushing and draining processes can be carried out; an opening for the immersion sensor enables an easy return temperature measurement.
