High efficiency air handling units for bol.com

Waalwijk, Netherlands

The new fulfillment center for bol.com has recently been completed at the Haven Acht business park in Waalwijk. In the design and construction, sustainability and energy efficiency have been optimally taken into account, in accordance with the BREEAM-NL outstanding certification criteria. Energy-saving installations for heating, cooling, ventilation and lighting will be installed in the building, including a heat and cold storage system, various windmills, LED lighting and high-efficiency air handling units with heat recovery, with a total capacity of 400,000 m³/h.

In 2016 Systemair B.V. in collaboration with the client Van Delft Installatie BV from Nieuwkuijk delivered a total of eighteen air handling units for the new fulfillment center, of which ten were HHFlex units with heaters and five recirculation units. The first contact for this assignment was made in 2016. Two weeks later, the first application was submitted to Systemair.

In accordance with the requirements of the specifications, the air handling units have been implemented with 85% high efficiency heat recovery, energy-efficient fans with IE4 motors, low box speeds, high media temperatures for cooling and low medium temperatures for heating, resulting in an ErP2018 with A-Energy-label. All units, varying from 8,000 to 40,000 m³/h, are equipped with a built-in control box and the necessary measuring and control equipment in our factory in Waalwijk. For this project the fans are controlled on the basis of constant channel pressure. The temperature is regulated at inlet temperature and there is a possibility for free cooling during the night. The control system manages all the safety devices of the unit.

Messages such as filter contamination, the risk of freezing of the battery and increasing pressure loss of the heat recovery give a service or fault alarm. The user has access to the list of active alarms and also a detailed history of all incidents. The units are included in the building management system through Modbus communication. The control constantly monitors all operating parameters and intelligently controls the operation of the various components for optimum energy efficiency. With which we meet all the wishes of bol.com.
