VKN SILENTFan assisted trench heaters. 10 cm height
2019_08
2 w w w . v e r a n o - g l o b a l . c o m
High thermal output complementing minimum noise level!Ideal for any rooms and chambers with the extreme low noise level requirement our fan assisted trench heaters add energy efficiency and high thermal output on the top.
We have modified the construction of the heat exchanger and used the different type of the fan impeller/motor. Everything we accomplished for quieter work and increased efficiency. Our newest 100 mm high VKN5 fan assisted trench heaters provide improved noise level, with the like other models’ thermal duties, respectively.
On the chart we present the comparison of the acoustic power for the selected frequencies. All figures have been included based on the results report no 4/2017 “VKN5 10/25 In-floor Fan Assisted Trench Heater Acoustic measures” and report no 5/2017 “VKN5 9/25 In-floor Fan Assisted Trench Heater Acoustic measures” both executed by Heating Department of the Energy Affairs Institute in Lodz/Poland.

OUR REFERENCE JOB FROM THE FIRST PAGE
• The National Parliament building in Warsaw/Poland
VKN SILENT fan assisted trench heaters operate as energy efficient heating emitters for this building.
ETO – Engineered to Order
The rooms and chambers in the Parliament Building required heating emitters with a total minimum noise level. We designed the brand-new model exclusively for this project to meet the highest and the most rigorous noise level requirements, usually the same that are for broadcasting rooms.

THE 230V AC – IP65 RATED CONNECTION SUPPLY MODULE
VKN SILENT ARE NOT ONLY FAN ASSISTED TRENCH HEATERS IN OUR RANGE
For thermomodernized buildings, it becomes problematic to provide additional 24 V DC low voltage installation. To avoid this problem, the power supply and connection module has been developed that allows the 230 V AC power supply to be connected directly to the heater trench. The internal connection box provides correct connection of the all electrical elements of the trench heater, further installation time on site.
The connection kit includes:• 230 V AC / 24 V DC Power supply • VER-927 Connection Box • 230 Electric Box• Heater trench extension of standard unit
The additional information about accessories for VKN SILENT, as well as the selection method, can be found in the VKN fan assisted trench heaters catalogue.
