Product catalog summary
Product Overview
Verano's VKN series fan-assisted trench heaters are designed for efficient heating through forced convection, suitable for residential, office, and commercial spaces. They respond quickly to temperature changes and are controlled by a room controller for energy efficiency.
Operating Principle
The heaters use forced convection, with fans enhancing airflow through a heat exchanger, increasing efficiency and heating power. This system allows for energy savings and reduced operating costs.
Advantages
  • High-efficiency heat exchangers boost heating output by 10-20%.
  • Modern EC fans ensure quiet, efficient operation.
  • Wireless control via mobile devices.
  • Adjustable tray positions for easy installation.
  • Customizable finishes and designs.
Specifications
Specifications for models like VKN1 and VKN5 include dimensions, equipment options, and materials such as copper-aluminum heat exchangers and EC motors. Trench heights range from 75 mm to 90 mm, widths from 250 mm to 350 mm, and lengths from 950 mm to 2750 mm.
Performance Data
Performance tables detail thermal power output, sound levels, and electrical power demand for various modes and trench lengths. Corrective coefficients adjust for different heating fluid and room temperatures.
Installation and Maintenance
Guidelines cover heater selection, wiring diagrams, and installation and maintenance instructions to ensure proper setup and operation.
Research and Development
Products are tested for high efficiency and EU compliance, designed to minimize drafts and suitable for low-temperature systems.
Control and Operation
Heaters operate at control voltages of Min (2V), Med (4V), Max (6V), and Boost (10V), with Boost for rapid heating. Corrective coefficients help select heating power based on grille type and temperature conditions.
Accessories and Installation
Standard equipment includes zinc-magnesium coated trays and fan covers. Accessories like assembly covers and temperature sensors are available. Recommended installation distance from walls is 100-300 mm.
Graphs and Data Interpretation
Graphs illustrate heating power, control voltage, and acoustic pressure relationships, aiding in performance understanding under different conditions.
Pressure and Temperature Limits
Maximum operating pressure is 1.0 MPa, test pressure 1.3 MPa, and hydraulic pressure 1.69 MPa. Maximum operating temperature is 110°C.
Heater Selection Guidelines
Guidelines assist in selecting heaters based on room heating demand, control voltage, and acoustic pressure levels, with example calculations provided.
Power Supply Considerations
Instructions for selecting power supply units based on electric power and current requirements, with examples for systems with multiple heaters.
Pressure Losses
Tables provide pressure losses related to mass flow and heat output for temperature differences from 5 K to 20 K.
Control and Operation
Automatic control via room regulator and thermal actuator maintains preset room temperature. Requires a room controller, thermal actuator, and 24V DC power supply.
Installation Guidelines
Installation involves preparing a trench larger than heater dimensions, leveling with floor construction layer, and using insulation materials with at least 70 kPa compression strength.
Safety and Maintenance
Installation should be done by licensed personnel. Heaters must use 24 V DC voltage. Regular cleaning of the heater tray is recommended.
Additional Information
Includes wiring diagrams for connecting multiple heaters to a single controller and emphasizes not covering heaters during the heating season.

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 or...
