Always a suitable solution

The VKT (Verhulst Thermal Units) is a custom-selected air handling unit, where the installer chooses to provide their own control technology and field equipment. Of course, if desired, we can supply and install the sensors and actuators. The VKT can be considered our most comprehensive ‘conventional unit’ and offers the best foundation for any project.

With the VKT, everything is possible

The VKT can be customized as desired, with all possibilities to manage the control technology and install field equipment yourself. Fully tailored to your needs, including complete project support. This air handling unit can be delivered in one piece, reducing or eliminating the need for coupling and hoisting costs. If desired, we arrange this with our trusted transporter/crane specialists. Since the VKT is modularly designed, it is ideal for replacement in existing situations. Complete assembly can be done on-site. We also support project preparation and calculators. BIM models are immediately available.

A tailor-made solution including control technology

The VKT Plus is a customer-specific selected air handling unit, including control technology. The wiring and piping are integrated, reducing installation time. With the VKT Plus, you opt for convenience! The VKT (Verhulst Kasten Thermisch) are our ‘conventional units’ and are delivered without control technology. The VKT Plus is the version with integrated control, and the Basic is the compact HR variant; both are fully ‘plug-and-play’. Are you looking for a complete air handling unit including control and cooling?

The VKT Plus is a plug-and-play unit with improved controls for indoor climates and lower energy consumption. The unit can be controlled remotely, and energy monitoring is available. Standard controls and tests are provided for the first commissioning, ensuring a quick startup and short lead times. Like the VKT, this air handling unit can be delivered in one piece, significantly saving coupling and crane costs.

Options for the VKT Plus

The VKT Plus, like the VKT (see the VKT brochure for details), can consist of the following components:

• Energy recovery
• Inspection sections
• Humidification section
• Fans
• Sound attenuator
• Heating
• Cooling
• Filters
• Project-specific support frame
• Technical room optional
• ATEX if desired
• Surface treatment for swimming pools
• Integrated control technology, piping, wiring, sensors, and actuators
• Energy monitoring
• Direct BMS connection through MODBUS protocol
• DX heat pumps
