Case Study: Deutsche Bahn
Use of heating units for the de-icing of trains for Deutsche Bahn in Braunschweig
December 2012: With a rented 400 kW mobile heating unit, DB Regio in Braunschweig found a way to de-ice its trains. Background context: over the last few winters, DB used to free its locomoti ves of up to two tons of ice and thawed them out with hot air in its engine sheds. However, that process could take up to 18 hours and culminated in a restriction being placed on train availability and therefore cancellations as well as delays. With the new soluti on from market leader Hotmobil Deutschland, up to 10,000 liters of water can be heated using the mobile heating unit and then sprayed on up to two locomotives at once in an engine shed measuring 50 meters in length – and it can do that right round the clock. The time required for the de-icing process has been cut to between four and fi ve hours according to statements by the technical staff at DB-Regio. The rail company added that trains bound for the Harz mountains stand to benefi t greatly from this heating unit, and this is the first time it has been deployed in Lower Saxony. In early 2013, aft er this new de-icing process had proven its capabilities, Deutsche Bahn ordered two heating containers from Hotmobil Deutschland. To enable them in future to remove ice from locomotives and trains at any time, and to have the ability to use the mobile power units for other purposes. The two heating containers, with power ratings of 630 kW and 2000 kW respectively , were produced in accordance with the specifications of this railway customer.
Frequently asked questions (FAQs) associated with the purchase of mobile energy units
1. Price indication
Can you name me a guide price?
HOTMOBIL: To enable us to give you a serious estimate of the anticipated costs for your individual system, our Project Managers need, as a minimum, approximate indications of your desired layout, as well as the equipment features you wish to have on your mobile power unit. Based on experiential values gained from the large number of customer-specific systems we have already installed, we can then give you a fairly accurate estimate of your anticipated costs. As a rule of thumb, for trailer-based units with a power rating of 150 - 950 kW, you can assume a basic price of around €35k to €65k. The price range for container-based power units with a power rating of 500 - 2500 kW lies in the region of €50k to €150k.
2. Design, dimensions and weight
How much space do I need to build into my calculation for a mobile power unit? How much does it weigh?
HOTMOBIL: In all cases, mobile power units are installed in special boxed trailers or in oversea or storage containers. We always strive to build these units as compactly as possible, on the basis of standard dimensions. Customized dimensions may however prove necessary in one-off cases. The weight of a mobile power unit depends on the desired power rating or the required components. As a useful rule of thumb, you can assume that trailer-based units with a power rating of 150 - 950 kW will weigh roughly 1.6 to 3.5 tons. Mobile container-based power units with a power rating of up to 2500 kW will tend to weigh between 3.5 and 8 tons.
3. Feedback control technology
What types of feedback control are possible??
HOTMOBIL: We plan and produce mobile power units individually to suit customer wishes. As a consequence, we are best equipped to adapt the feedback control system on the unit to the building it will ultimately be serving with mobile power. Across the board, all types of hydraulic circuit and feedback control system are feasible. Also, when needed, the unit can be connected to in situ feedback control systems. Based on your requirements, our Project Managers will be pleased to devise and offer an appropriate feedback control concept.
4. Expansion Vessels
Which expansion vessels are used?
HOTMOBIL: Across the board, all kinds of expansion vessel are feasible. The choice of expansion unit does however have a significant influence on the ultimate size of the overall system. A decisive point is whether protection is required on just the heat generating circuit, or also on the consumer network. Depending on requirements, either a compressor-controller expansion vessel or a static one, with the addition of automatic refill and/or gas relief/evacuation may be needed. To comply with directive VDI 2035, a water treatment unit is also a required element.
5. Connection options
Which connections are present on the unit at which location(s)?
HOTMOBIL: The interfaces for heating water and, when necessary, for domestic hot water are fitted as standard on one of the external walls of the unit. The connections for power supply, condensate and fuel fill are normally inside the unit for safety reasons. Where technically feasible, we will also be pleased to cater for any individual placement wishes you may have. The connection dimensions correlate with the performance rating of the unit, and its corresponding volumetric flow rate. Regardless of this, the type of connections can be selected to provide a precise match with your preferences, meaning that external threads, flanges and all kinds of quick-release couplings are possible.
6. CE conformity
Is the unit CE-compliant?
HOTMOBIL: Yes! All of our units comply with the latest applicable standards and specifications, and are duly identified as such.
Which accessories are required?
HOTMOBIL: You never need to provide us with accessories of any kind. All of our individually produced mobile power units are independent, standalone systems, each one precisely matched to your needs and on-site conditions. Once connected up to the required media supply points, i.e. with electricity, water and fuel and/or condensate, the unit is ready to run. In cases where your individually produced unit is intended for use at different locations, flexible hose material may be required for connection to these systems in certain cases. Whenever required, our Project Managers will be delighted to discuss all of this with you in advance.
8. Water quality standards
Is a water treatment facility mandatory?
HOTMOBIL: VDI 2035 is the directive that deals with the prevention of damage in hot water heating units. If at the planning stage, no fixed installation for water treatment has been envisaged, we are also able to fill your unit directly on site with standard-compliant treated water.
9. Delivery and delivery lead time
How are units delivered to site? How fast can you deliver?
HOTMOBIL: When needed, we are pleased to arrange transport together with any crane/lifting equipment that may be required, and can also offer on-site commissioning as an optional service. For individually produced units, depending on their level of complexity and on the utilization level of our production facilities, you should assume a delivery lead time of between 4 to 10 weeks or thereabouts. Regardless of our delivery lead time, we are always in a position to provide you with immediate effect with a unit from our rental fleet.
10. Sale of rental units
Is it possible to purchase rental units?
HOTMOBIL: Certainly, the sale of a rental unit is always an option. Please contact our Project Managers directly whenever you need their assistance. We will be delighted to check the availability of the desired unit, and can provide you with a quotation in respect of purchase of any rental unit.
