Future-proof storage thanks to modern ventilation technology for O. Dold Speditions- und Transport GmbH
airinotec has comprehensively modernized the ventilation technology of a high-bay warehouse for O. Dold Speditions- und Transport GmbH. The use of efficient heat pumps and intelligent control technology has not only created the basis for storing temperature-sensitive products such as chocolate, but also significantly increased energy efficiency—during ongoing operations and under challenging structural conditions.
Optimization of ventilation technology in a high-bay warehouse through the use of two redundant heat pumps
O. Dold Speditions- und Transport GmbH is a renowned logistics service provider based in Rhineland-Palatinate. The company specializes in transportation and offers comprehensive logistics solutions for a wide range of industries. With a history dating back to the 1960s, Oskar Dold Speditions- und Transport GmbH has become a leading player in the industry through continuous innovation and customer focus. Today, the company employs over 100 people who ensure that goods reach their destination on time and safely every day. Oskar Dold Speditions- und Transport GmbH is proud of its modern warehousing and logistics facilities, which enable a wide range of services – including the storage of temperature-sensitive products such as chocolate and confectionery.
Modernization of ventilation technology for temperature-controlled storage
As part of this project, the ventilation technology in the high-bay warehouse of Oskar Dold Speditions- und Transport GmbH was successfully modernized and optimized. The aim was to ensure a constant room temperature through the use of modern ventilation systems and heat pumps in order to enable the storage of temperature-sensitive products. The implementation was completed on schedule by November 2024.
Installation of modern ventilation units with heat recovery
The ventilation system in the high-bay warehouse was significantly improved through the installation of two modern ventilation units. These units, which were placed outside the warehouse at the front, are equipped with single-stage filtration (filter class F7) and a heat exchanger for heating and cooling.
Efficient cooling and heating thanks to redundant, air-cooled heat pumps
Two redundant, air-cooled heat pumps were installed to supply the heat exchangers for heating and cooling in the ventilation units. These are located in the immediate vicinity of the ventilation units and contribute significantly to efficient and sustainable cooling and heating. In winter, the system ensures constant heat, while in summer, reliable cooling is guaranteed.
Innovative duct routing for optimal air distribution
The supply air was fed in via a duct system above the shelving system, while the exhaust air was extracted at specific points in the lower front wall area. A special feature of this project was the option of subsequently expanding the supply air duct system to allow for a possible extension of the shelving system.
Fastening and insulation of the air ducts
The supply air ducts were fastened in the area of the shelving system either to the shelves themselves or to the ceiling/roof structure. In the pre-zone, the ducts were also fastened to the ceiling/roof structure, while the riser ducts in the outdoor area were mounted to the supporting structure of the facade. The ducts in the outdoor area were insulated with insulation and a sheet metal jacket.
By installing redundant heat pumps, we are creating a future-proof solution that allows our customers to store temperature-sensitive products safely while reducing operating costs.
Automation technology for precise control of the ventilation system
A Siemens Simatic S7 PLC/DDC control system was used to control the entire system. The control cabinet for the ventilation system was placed outside the high-bay warehouse in an enclosure next to the recirculation units and is operated via a touch panel on the control cabinet. The complete electrical cabling from the control cabinet to the ventilation units, room temperature sensors, immersion temperature sensors, and the pumps and control valves of the cold and hot water system was part of the order. The order also included the piping, including insulation, from the heat pump to the heat exchangers in the ventilation units, as well as an additional enclosure for the pumps. The complete commissioning of the ventilation technology, including the heat pumps, was successfully carried out. The system was designed in accordance with VDI 6022 hygiene standards.
Efficient installation planning and execution
An important aspect of the project execution was efficient installation. This was carried out during normal working hours to avoid additional costs. A crane provided by the client was used to position the ventilation units, heat pumps, and ducts in the outdoor area. The installation process was carefully planned to minimize disruption to operations in the high-bay warehouse. A special scaffolding concept was also developed for this purpose.
Expansion of the product range and energy efficiency
The customer benefits of this modernization are particularly noteworthy: thanks to the optimized ventilation technology, the high-bay warehouse can now store temperature-sensitive products such as chocolate and confectionery, significantly expanding the product range. In addition, the use of heat pumps ensures efficient and sustainable cooling and heating, leading to long-term cost savings and improved energy efficiency.
Successful optimization by airinotec
This project impressively demonstrates how existing storage infrastructures can be optimized and adapted to new requirements through the use of modern ventilation technology and intelligent control systems. The successful implementation within the planned timeframe underscores airinotec's expertise and reliability in the field of technical building equipment.
