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 microand 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 benefits 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.

*Power levels and types are dependent on flow rate and spread
