WCU-series

Product catalog summary

Introduction to Schwank WCU-series:
The Schwank WCU-series consists of destratification fans designed to effectively recirculate warm air within a room, enhancing energy efficiency and comfort. Key features include high efficiency, energy savings, extra recirculation, even heat distribution, increased comfort, and reduced temperature gradients. An optional EC motor is available for improved energy efficiency.

Importance of Destratification Fans:
With stricter building regulations and rising energy costs, industrial buildings are better insulated, reducing the need for heating capacity. Efficient heat recirculation becomes crucial, and Schwank Circulation Units are ideal for this, especially when used with Schwank XR or HR indirect fired heaters.

Advantages of Destratification Fans:

Decrease in temperature gradient
Reduced transmission losses
Energy savings of 10-30%
Increased comfort
Shorter heat-up time
Extra ventilation in summer
Easy suspension

Energy Savings:
Research by Gasunie indicates that gas consumption can decrease by 20-30% with adequate destratification fans (recommended: 1 fan per 300m²). Without these units, temperature differences between ceiling and floor can be significant, but with fans, the temperature increase is limited, reducing heat loss and maintaining floor warmth longer.

Optional EC Motor:
The WCU fans can be equipped with an EC motor, reducing electricity consumption by approximately 25% compared to standard AC motors.

Selection and Positioning:
The selection of WCU types depends on hall height, recommended for buildings over 5 meters. The number of units is determined by multiplying hall volume by circulation rate, subtracting existing recirculation volume, and dividing by the WCU's air output. Fans should be placed at the end of the heater's throw to prevent air whirling.

WCU Range:
The WCU range includes four types with air outputs from 3,200 m³/h to 10,000 m³/h. They feature thermostats to activate fans when ceiling temperatures rise, adjustable louvres, and a 5-step switch for speed and noise control. Easy suspension is facilitated by chains and eye bolts.

Technical Data:
Technical specifications for WCU models include air output, fan diameter, power consumption, absorbed current, electrical supply, revolutions per minute, sound levels, and weight. For example, the WCU40 has an air output of 3,200 m³/h, a fan diameter of 350 cm, and a power consumption of 170 W.

Stricter building regulations and increasing energy prices have resulted in industrial buildings which are increasingly better insulated. As a consequence of this, less heating capacity is required to heat up a building. For energy saving purposes this is very positive. However, the relevance of an efficient and effective recirculation of the heat present in the building increases significantly. The Schwank Circulation Units are perfectly suitable for this purpose, especially in combination with the indirect fired heaters Schwank XR or HR.

Always position destratification fans at the end of the heater’s throw (to avoid whirling of the air) or above an area where no air is blown to by the heater. Selection of the right type of WCU depends on the height of the hall. Application of WCU’s is always recommended in buildings higher than 5 meters. To determine the number of units, multiply the hall volume with the circulation rate. Deduct from the result the volume of recirculation already available, for example created by heaters. The WCU range consists of 4 types with air outputs from 3,200 m3 to 10,000 m3. They are provided with a...
