Panel collectors HEWALEX KS

Technical specification

Description
The collectors from KS series are equipped with aluminum-copper absorber (aluminum sheet + copper pipes). Covered with EtaPlus - highly selective layer by the German company Blue Tec. The hull is made out of single piece of aluminum in order to reduce the number of welds and it is protected with patented structured glass with high coefficient of conduction of sunlight 91.6%. The laser welding used in the collectors provides continuous and sustainable connection of copper pipes and aluminium absorber elements and is able to withstand high thermal loads. The collectors are a subject of detailed tests for quality and energy efficiency in accordance to the certificate Solar Keymark (011-7S1693 F).
Application
The flat solar collectors, KS series are designed for the heating of domestic hot water and pool water and for powering the central heating systems.

Accessories
Grua pump controller with ZPS 18E-01|
The module provides flow rate of the heat transfer, protection and control on 17 specified diagrams with the help of a microprocessor controller G422-P06. Designed to work with systems with flat and vacuum solar collectors with a volume of 18 liters per minute. The electronic flow meter allows  precise tracking of the parameters of the heat transfer and reporting of energy savings from the solar collector for the last 60 days, 20 weeks, 12 months, 10 years.
X-shaped fitting with well and air vent
Consists of air vent, 30 mm hexagonal nut ¾" threaded, socket temperature sensor and sealing.
Kappa KS ¾"
Kappa made out of brass specialized to seal the unused openings of the collectors.
