Pressure-resistant
fans

Our VARIO fan series in two designs is adjusted to requirements by means of a frequency convertor. The HSR fan series is particularly pressure-resistant, which provides the basis for a successful hay drying plant. The fans with powder-coated, stable steel housing and additional turbine paint finish in the Vario Elite model guarantee long life expectancy and ensure consistent air flow.

15 Highlights

Quiet-running fans

Quiet-running fans

The VARIO fan series is particularly quiet and is therefore suitable for installation in the living area or in farmyards, which have a guest house or holiday accommodation business attached.

Steel sheet wall

Steel sheet wall

The robust steel sheet wall of the HSR fan guarantees long life for the fan. The fan itself is secured to a stable steel structure.

Frequency converter

Frequency converter

The VARIO fans (VARIO ELITE and VARIO) are continuously regulated by means of a frequency converter, which ensures that the fan runs within the ideal speed range.

Air intake grill

Air intake grill

The particularly fine mesh of the air intake grill ensures low suction resistance,. which prevents air turbulence.

Inspection port

Inspection port

From fan size SR 900 onwards all the fans have an inspection port on the upper rear part of the fan. This is protected by a child lock.

Vane wheel position

Vane wheel position

Our VARIO Elite and VARIO fans have a specifically designed vane wheel position, which is perfectly calibrated to the air volume requirement for drying hay.

Tips for installing the fan

Each hay drying plant is unique and so good planning is essential. The correct implementation of the plan is primordial for a proper drying process.

Example: A fan must move 60,000 m³ of air into the hay box. A HSR representative selects the appropriate fan. However, if there are structural defects and the fan stands too close to the wall and cannot take in the required volume of air, the haystack collapses, the material becomes compacted and intervention by the fire service will be needed.

In order to avoid mistakes in installation and planning, we have developed an 80-page document for planning support, which explains the most important ground rules for barn construction. This document is provided to our customers on purchase of our products.

Here are a few tips on installation of the fan:

  • Ensure the fan has sufficient space to take in the air.
  • The fan motor must not be located within the air flow (over-heating, air turbulence).
  • The frequency converter for the fan must be mounted external to the fan chamber.
  • For the cooling of the motor it is recommended that a Polokal pipe (HT pipe) is led to the motor from outside. The motor automatically takes in fresh air via the negative pressure.
  • When ordering, note must be taken of the fan's exhaust opening.

Housing positions on HSR fans

Every HSR fan can be ordered in 16 different designs (positions). The designs differ in the position of the motor (left or right) and in 45% gradations for the exhaust opening. Note: The dimensions also change with the respective exhaust opening.
