FORCED CONVECTION Heater frame Finishing layer Floor mat Cement (screed) Floor insulation layer Floor structural layer Floor styrofoam, e.g. EPS70 Levelling and fastening anchor Lattice Heater tray Return to C.H. installation C.H. installation connector Heater power and control cables OPERATING PRINCIPLE OF FORCED CONVECTION TRENCH HEATERS Convection heating systems utilize the phenomenon of heat absorption by air particles flowing through heat exchanger. The difference in densities of cold and heated air causes a delicate draft that initiates the airflow in the exchanger. Use of fan allows...

HIGHLY EFFICIENT HEAT EXCHANGER Research and development works allowed us to optimise sizes for heat exchangers. As the result of that we have increased the product heating output by 10 to 20%, depending of the unit length and height. DEDICATED CONTROL SYSTEM Modern room controllers allow for full control of heater operations. MODERN EC FANS Using 24V DC fan motors will provide much quicker and quiet air distribution, yet the entire product is safe and hassle free for install and maintenance. WIRELESS CONTROL Now it is a child’s play to precisely control the heaters with use of your mobile...

CONFIRMED QUALITY Years of thorough research, analyses and measurements, including those in the Warsaw, Cracow and Lublin Universities of Technology, Polish Academy of Sciences and own research we developed high class heating and heating-cooling devices. They increase the energy efficiency of hot / cold air supply and significantly increase the efficiency of low-temperature systems that they work with. The perfect technical parameters of Verano products were also confirmed in the tests conducted in the HEATEST s.r.o. notified body and the Heizung – Lüftung – Klimatechnik Stuttgart at the...

Trench length Normative heating power output [W] compliant to EN-16430 for room temperature of 0 = 20°C. Control voltages for the respective modes of operation: Min - 2 V, Med - 4 V, Max - 6 V, Boost - 10 V. Min, Med, Max fan speeds are for continuous operations, the Boost mode for fast additional heating of rooms. Sound power level according to ISO-3745 standard, sound pressure level for a distance of 2m in a room of a total volume of 100 m3 and reverb time of 0.5 s assuming room dampening of 8 dB(A).

HEATING POWER AND ACOUSTIC PRESSURE OF VKN1-6,5/14/Lk The graphs present how heating power Φ [W] depends on the respective average temperature differences ΔT [K], for control voltages U [V]. The graphs also present the acoustic pressure levels for the respective heater operating conditions. NOTE! An example readout of control voltages and acoustic pressure for different values of heating power is included in page no. 40.
