PIPING SYSTEMS

KELIT PEX 95-6

Provides a pre-insulated flexible plastic pipe system with PEXa cross-linked polyethylene carrier pipes and PUR (CFC-free) thermal insulation for district heating applications.

A PEXa SDR 11 carrier pipe with oxygen barrier is used for KELIT PEX 95-6 with a maximum short term operating temperature of 95°C. For continuous operation, a maximum of 6 bar and 80°C is allowed.

The system is jacketed with corrugated PE-LD pipe, manufactured by seamless extrusion. In order to further reduce heat losses, a second insulation series with a higher level of insulation is also available.

KELIT DUO PEX 95-6

The duo offers all the same attributes as the standard KELIT PEX 95-6 however it consists of two PEXa SDR 11 carrier pipes.

KELIT PE FLEX

Provides a pre-insulated flexible plastic pipe system with PE 100 polyethylene carrier pipes, in order to guarantee drinking water safety a CO2 based polyurethane PUR foam (CFC-free) is used for insulation. 

A PE 100 SDR 11 carrier pipe is used with a maximum working pressure of 16 bar at 30°C for continuous operation.

For applications where the ambient temperatures are below freezing, the pipe system is optionally available with a self-regulating frost protection system.

The system is jacketed with corrugated PE-LD pipe, manufactured by seamless extrusion.

THE KELIT PEX SYSTEM CAN BE USED IN THE FOLLOWING APPLICATION AREAS

• District Heating applications, the maximum temperature of 95°C. Maximum continuous operating temperature 95°C - 6 bar.
• Cold Water applications can operate between -20 to 30°C with a maximum operating pressure of 16 bar.

MATERIAL - CARRIER PIPES

KELIT PEX 95-6 has a single cross-linked polyethylene PEXa SDR 11 carrier pipe.
KELIT DUE PEX 95-6 has two cross-linked polyethylene PEXa SDR 11 carrier pipes.
KELIT PE FLEX has a single high-density PE 100 SDR 11 carrier pipe.

MATERIAL - THERMAL INSULATION

All three KELIT PEX systems have polyurethane (PUR) foam insulation which is CFC-free.
PEX 95-6 and PE FLEX systems boast an outstanding thermal conductivity of ≤ 0.0210 W/mK and ≤ 0.023 W/mK respectively.

MATERIAL - JACKET PIPE

All three KELIT PEX systems have corrugated PE-LD pipe, manufactured by seamless extrusion.
