8. ADDITIONAL HOT WATER COIL OPTION

8.1. Introduction

Heating heat exchangers with warm water are equipments that could be used optionally in all series of
URTP devices. While completely mounting the device, there are 3-way valve and servo motor in standard
on the unit delivered. The desired capacity could be reached by this means by doing water flow rate
modulation. The heat exchangers in use were tested under 22-25 bar pressure and cause no efficiency
problem for the conditions of use. With this option, low temperature thermostat has been involved in the
system and user is warned by the system when the temperature drops under 5°C.

8.2. Pipe Connections of Heating Water

The table belonging to hot water coil pipe connections distances and diameters for all URTP models are
given at the table below. Before making these connections, cut-off valves should absolutely be placed on
water inlet and outlet lines. Besides, any kind of dirt, air and sediments to come from the installation,
sediment and dirt strainer and air discharge purges should be placed at the system inlet. Clearing the heat
exchangers and the installation off dirt and sediments will prolong the device life and besides, enable the
values to be acquired throughout the whole operation period to be the parameters displayed at the catalogue.
The mentioned sample installation schema is given below.
