Simon Howie Foods started in 1986 and is now one oft he leading manufactureres of quality meat produts which are sold throughout thousand of shops in Scotland, England, Ireland as well as exports to other countries.
One of the main cost component in the produciton of these products is energy. Some 3.000 kWh a day are just needed for the production of hot water. Many other devices (cooling) depend on electricity. Simon Howie made the decision to invest in a PV system to reduce the dependance on the local supply of electricity due to substancial increases in electricity. The system consists of some 3,500 panels and the associated infrastructure. Our involvement was the challenge to store thermal energy and supply hygenic hot water for the operation.
Since further expansions are expected it was decided to place two tanks (12,000 litres, 14,200 litres), each fitted out with 3 x 9 m2 INOX heat exchangers for the preparation of hot water.
Our tanks are able to use multiple heat sources, even heat recovery. For the initial primary heat supply an external heating sytem, based on electric elements, was selected.
This system can supply 180 kW/h to each tank and has a smart monitoring system to guarantee high efficiency. We are also examining the possibility to recover sustancial thermal heat from their 24/7 running refrigeration systems.
The project has exceeded the owner’s expectations, is running smoothly and is now even to be extended. The design is based 100 % on a draft by our long-standing consultant Hermann Bauer. We are very proud to be part of this project and thank Simon to give us this opportunity!

The installation of a hot water tank from Haase was worthwhile for the Hamburg city cleaning (SRH). After converting the heating system, the previously unused waste heat from the server room is now being used. This is used to heat shower and drinking water and also supports the heating system. At the same time, the effective use of waste heat ensures the previously complex cooling of server operation. By renewing the system, city cleaning Hamburg was able to save 500,000 kilowatt hours and thus 81 tons of CO2 last year. That roughly corresponds to the heating requirements of 90 modern terraced houses.

Graduate engineer Dominik Iskenius-Eggers, who has supervised the project from the start, sums up how successful this investment is for Hamburg’s city cleaning: “This example thoroughly disproves the frequently used argument ‘ecology does not pay off’. The hot water requirement can be met all year round via the data center, so that the heating network can be switched off completely in summer, “continues Iskenius-Eggers.

The climate protection officer of the SRH, Dr. Stefan Lübben, continues: “The project was more successful, the savings were much higher than we had expected.” In this way, the previous calculations could be corrected with a payback period of ten years to around three years.

A common problem: The fat separator made of PE, 17 years old, was cracked and therefore irreparably damaged. The daycare center in Dresden could suffer immense damage if a new grease trap were not put into operation as quickly as possible.

The daycare center attaches great importance and is proud to produce up to 150 healthy meals a day from fresh ingredients in its own kitchen. A replacement for the defective grease separator had to be found as quickly as possible. The biggest problem: The bunker, in which the old separator and the lifting system were located, is only accessible through a hatch with the dimensions 60 x 80 cm. The bunker was built 17 years ago, the separator was placed in it and then a 70 cm thick concrete ceiling was pulled over it. Of course, this would have been completely unacceptable in terms of both time and money for changing the separator.
The alternative: the on-site and freely erectable fat separator from Haase. The finished separator for this construction project with the nominal size 4 has a diameter of 100 cm and a height of 170 cm, nevertheless it fit through the tank hatch because it was installed in individual parts and then assembled.
A special plus: assembly can be completed within one working day.

The fat separator at the Mayr butcher’s shop in Upper Bavaria had to be replaced due to severe concrete corrosion and increased wastewater volume. The particular challenge was that the only possible installation location for the separator system was directly on the building wall. In addition, the narrow street could not be opened more than 0.50 m from the edge to allow access to the cul-de-sac at any time.
The installation situation in connection with the large inlet depth of 2.40 m made it impossible to install a new separator made of concrete or PE. The task was solved with a fat separator made of glass fiber reinforced plastic (GRP). The system can withstand high static loads and, unlike PE separators, can also be installed with a large earth cover. The low weight compared to concrete separators made it possible to move with an excavator, despite the tight installation conditions.
The extended dome shaft with a diameter of 1.00 m has already been factory-fitted to the separator system. This means that the fat separator has no weak points in the form of joints and passed the leak test without any problems during initial commissioning.
The system could therefore be installed quickly, so that the butcher could start operating again within a few hours.

For an internationally leading manufacturer and provider of products and services related to compressed air, the company Angermüller Bau GmbH has built an extension on the company premises in Coburg. A reloading point for the operating oils of the compressors was also set up in the delivery area.

The specialty for the required light liquid separator was that the 9 different oils with densities in the range of 0.860g / cm³ to 0.985g / cm³ were retained. Since light liquid separators work mainly due to the difference in density and water is known to have a density of approx. 1 g / cm³, oils with a density above 0.95 g / cm³ cannot be safely retained.

Because of this, a safety collecting tank was installed in front of the light liquid separator. The electrical control was installed professionally by the Müller workshop service. During the handling process, the flow tube is automatically closed by the butterfly valve, so that the oils are retained in the safety collecting tank in the event of an accident. Rainwater, on the other hand, can run freely through the piped basin into the separator.
The safety collecting tank and the light liquid separator are chemically permanently tight and resistant due to the properties of the glass fiber reinforced plastic for the operating oils used.

A large mineral oil dealer with several hundred petrol stations in Sweden and Denmark relies on the permanently sealed and durable light liquid separators from Haase. The decisive factor in the company’s decision was the premise of being able to offer customers consistently low fuel prices. The GRP separator from Haase fits this company philosophy, because its operating costs run to zero due to the seamless tank structure and the material of glass fiber reinforced plastic. In contrast, concrete products always come with considerable renovation costs, as the coating wears out over the years and shaft joints become leaky. In addition, the petrol stations for separator refurbishment must be taken out of service, to the detriment of customers and operators.

The height of the seamlessly laminated shaft can also be adjusted on site at any time. Another advantage is the light weight and compact design of the Haase separator. This enabled the system to be transported inexpensively by a freight forwarder, and the heavy-duty transport that was usual with concrete separators was not necessary. Unloading was straightforward with an excavator. An easy entry and thus a quick and uncomplicated inspection is possible via the cathedral shaft.

Glass fiber reinforced plastic is permanently durable, easy to process and can be prefabricated over a large area, which significantly reduces the renovation and thus downtimes. These were also the decisive reasons for the operator of a composting plant to renovate 2 concrete seepage water pools, each with a volume of 475 m³, with GRP. The pools each have a diameter of 11 m and a height of 5 m. Since one basin must always remain in operation to maintain composting operations, the two basins are renovated one after the other. The prefabricated board laminates were delivered to the construction site as rolls, anchored there on the walls and on the floor and overlaminated at the connection points. To prevent water from penetrating between the GRP lining and the concrete wall, the laminate panels are screwed to the wall in the upper area and provided with a permanently elastic sealant. Finally, the lining was coated with a RAL color. Pump sumps and the pipelines were of course included in the renovation.

For an Austrian fruit juice manufacturer, in addition to the highest product quality, the responsible use of natural resources is paramount. An important building block for this is energy efficiency – the production should take place with the lowest possible energy consumption. The company therefore works consistently to avoid heat loss and to use previously “wasted” waste heat.

For this purpose, two Haase containers were integrated into the water supply. For this purpose, heat is extracted from the 19 ° C cold process water by a heat pump and pumped back into the cold storage at a temperature of 12 ° C. With the energy gained, the 86 ° C hot water from the return of the production process is heated by approx. 7 ° C and temporarily stored in the Haase hot water tank until it is used. The medium heated to 93 ° C is then used for several different hot water lines, for example for disinfection or cleaning processes.

We delivered two factory-made flat bottom tanks for the logistics center of a nationwide retail chain in Koblenz. Engine oil is stored in them, which is used for the connected cogeneration unit.
The planning company commissioned by the operator had taken into account right from the start that Koblenz was located in earthquake zone 1 and that the storage tanks for water-polluting liquids must also have the appropriate approval. Other requirements for the flat-bottom tanks were double-walled, high temperature resistance and long-term resistance to the medium. The switchover option between the tanks enables the CHP unit to run uninterrupted even during an oil change.
