TDU.5 floor distribution unit

General description and application

Typ e 1 Typ e 2

General operating parameters

The TDU.5 floor distribution unit is intended for two pipe horizontal heating systems and includes connecting, measuring, regulating and distribution functions.

The TDU.5 is easily installed on the wall surface and connected to the riser of heating system. The apartment horizontal heating systems are connected to the branches of the unit. Design of the TDU.5 provides convenient access to all the elements thus simplifies system adjustment. The TDU.5 floor distribution units are manufactured with 2–6 circuits (left-hand / right-hand versions). All manifolds are factory insulated with 13 mm elastomeric insulation.

Design temperature °C 95

Design pressure bar 10

Test pressure, bar 16

Maximum differential pressure in the risers bar 1,5

Setting of differential pressure in the apartment heating system kPa

Connection to the risers (3 variants) Rp ¾; Rp 1; Rp 1¼

Connection to heating system of apartments Rp ½ – return line

Standard TDU.5 consists of: On main manifolds DN50

• Automatic balancing valve – differential pressure controller ASV-PV

• Partner valve with flow limitation function ASV-BD

• Strainer

• Shut-off valves

• Drain

• Deairing

On branches DN15:

• Heat meter inserts for each apartment

• Type 1: Manual balancing valves USV-I

• Type 2: Control balancing valves RA-HC

The TDU.5 floor distribution units are manufactured with 2–6 circuits (left-hand / right-hand versions).

Accessories:

• Cabinets

• TWA actuators for RA-HC

• Room thermostats

• Energy meters

* Overall dimensions in width, depth and height depend on the installation position.

It is allowed to mount the unit without a casing with the collectors displaced vertically and horizontally within the length of the ASV-PV impulse tube, while maintaining the possibility of its mounting and dismounting (impulse tube length is 1.5m). The minimum recommended vertical distance between manifolds is 200 mm.
