Dzhuma Mosque, Tashkent, Uzbekistan

Ice and snow melting system

Dzhuma Mosque is a mosque in Tashkent, Uzbekistan; it is also known as the Jama Mosque. It was built in 1451 by Sheikh Uboydullo Khoja Akhror.

Ground ice and snow melting solutions

A ground ice and snow melting system was made for 1,938 m2. The output of the system is 508 kW. DEVIsnow™ 30T heating cables were used. One part of the system will be regulated by DEVIreg™ 850 thermostats and another part with DEVIreg™ 330 thermostats.

Roof and gutter protection

The roof and gutter ice protection system was installed in gutters with a total length of 844 m. The output of the system is 46 kW. DEVIsnow™ heating cables were used. One part of the system will be regulated by DEVIreg™ 850 thermostats and another part with DEVIreg™ 330 thermostats.

Heating cables
Backend.Models.ProductViewModel.Title
DEVIsnow™ is an extremely high-quality, 360° fully screened twin conductor cable with a tough outer sheath (UV stable). Its round profile and robust construction ensures a fast, simple and safe installation on roofs, in gutters, down drain pipes and on the ground. The cold lead has solid conductors ensuring fast installation with a clearly visible connection. To ensure a long life-time, all cables are minutely inspected including tests for Ohmic resistance, high voltage and material controls to ensure the quality. This means that we are proud to supply our extended DEVIwarranty™.
Thermostats
Backend.Models.ProductViewModel.Title
The DEVIreg™ 330 is an electronic thermostat to be installed in electric cabinets with DIN rail attachment. Used primarily for controlling a lower temperature range as by frost protection. The thermostat must be installed via an all-pole disconnection switch and has a LED indicating the current mode (heating, standby or fault). To measure and control the desired temperature a wire sensor or an outdoor air sensor must be used. The temperature setting can be adjusted with a scale from -10°C to +10°C.
Backend.Models.ProductViewModel.Title
The DEVIreg™ 850 is an advanced thermostat with LED display used for outdoor ground or roof applications. The sensors provide information about both moisture level and temperature, resulting in an optimal control of the heating system. The system can be set up in three ways; as a single system for roof or ground (1 to 4 sensors), as a dual system for roof or ground (2 - 4 sensors) or as a combination system for roof and ground (2 - 4 sensors). In the dual / combination systems it is possible to prioritize between the zones, e.g. if only a limited power output is available.
