Danfoss UNISTAT 1016 WR Fact sheet
Fact Sheet
UNISTAT 1016 WR Small
Compact district heating substation from 16 to 30 kW*
Application
The UNISTAT 1016 WR is designed for
use in district heating networks. Depending on type, it can be used both in
micro- and macro-networks, in low temperature (LT) and high temperature (HT)
ranges. The substation is an innovative
product which sets industry standards.
Function
The communicative controller ECL 310 is
used. This controller ensures optimum
regulation of the energy distribution.
The supply temperature for the domestic system is weather compensated.
Energy consumption and temperatures
can be remote monitored.
Construction
The built-in components are connected by means of precisionmanufactured
welded steel pipes. The PN25 version
is featured with welded carbon steel
pipes on primary side and stainless
steel pipes on secondary side. High
quality gaskets are used as sealing
material. The entire water-bearing part
of the substation is thermally insulated
(EPP). This design enables an easy and
quick removal for service purposes.
The benets of this design are:
- Minimal radiation heat losses
- High durability
- Mounting option for pressure
and temperature measuring
instruments is incorporated.
Assembly
The compact substation is easy to wallmount.
