Internal tank cleaning

A squeaky-clean technology: With our highly motivated and qualified team, we design, construct, and implement all the components and plant parts required for internal tank cleaning; from water treatment to high-pressure technology to plant automation, from safety and environmental technology to customized IT. Let the following pages inform you a little about the many aspects to be considered in this technology, which is only dirty at first glance, but which is in fact important to all of us and clean as a whistle. And perhaps you will also be inspired by the perfectionism with which we can optimally prepare your tank containers and permanently installed tank cleaning systems for the next filling.

Water treatment

A clear thing! We design and install complete water softening and reverse osmosis systems to meet the highest water quality requirements. Water softening with water filter and system separator protects all water-bearing systems from lime deposits and other pollutants that can lead to functional impairment or system failure. Reverse osmosis is used in steam boiler systems and provides controlled soft water. We manufacture water treatment plants entirely according to customer requirements in standard or special sizes, receiver tanks for cold and hot water made of plastic or stainless steel, with or without insulation. Pre-assembly takes place as far as possible in the workshop, installation and activation on site goes without saying.

Hot water and steam supply

Full steam ahead! A lot can be done with steam, e.g. efficient, energy-saving and reliable hot water preparation with up-to-date equipment on both the suction and pressure side. In smaller purification plants, demand-oriented and economical high-pressure instant water heaters are used, and significant energy savings are achieved by recovering wastewater heat and flue gas energy. We build compact heat exchanger plants made of stainless steel in closed design, which are easy to clean and odor-free. Hot air systems for drying vehicles and containers also work with steam, which is also used for heating and disinfecting tanks or tank wagons, for controlled heating of temperature-sensitive products and much more – contact us regarding your requirements!

High pressure technology up to 500 bar

We work under high pressure! When the usual cleaning performance up to 100 bar is no longer sufficient, our ultra-high-pressure plants up to 500 bar with world-leading technology come into play. Our expertise in plant engineering is synergically complemented by the experience of our industrial partner as market leader in the ultra-high-pressure sector. We manufacture customized, low-maintenance and stationery ultra-high-pressure systems as stand-alone solutions or in combination with our plant engineering and install smooth-running, reliable yet powerful pump technology both for flushing head operations but also for use with hand lances and other cleaning tools. Assembly and activation are carried out by experienced pump fitters.

Detergent dosage

The dose makes the effect! Optimal cleaning performance with simultaneous economic efficiency is achieved with our automated dosing systems on the suction and pressure side of the pump technology with different pump types depending on the place of use. We design and manufacture completely pre-assembled dosing systems with base frame, storage tanks, change-over valves, and pump technology, depending on the product and application, as a specified design. This also includes intelligent drains to achieve good wetting in the tank and to ensure sufficient contact time of the cleaning agent. Also included are circulation cleaning systems for the treatment of particularly stubborn soiling such as latex or resins.

Put on the right track! In close consultation with the customer, we advise on the type and scope of cleaning and, depending on the product and vehicle, we put together suitable flushing head equipment for internal tank cleaning as well as sensible equipment and design of the cleaning track. We design and manufacture special flushing heads for web tank cleaning, circulation cleaning, telescopic cleaning and ultra-high pressure cleaning directly on the tank wall. In addition, we manufacture auxiliary equipment such as hose trolleys, fitting cleaning tables, transport hose dryers as well as shifting stations for different rinsing head applications at one washing station and much more. All made of high-quality materials and conceptualized for a long service life, naturally.

Exhaust air treatment

Well ventilated! Some products, e.g. containing solvents, require the extraction and subsequent treatment of the vapors generated during internal tank cleaning. We take care of the correct design and operation of the downstream exhaust air treatment system and build gas cooling and scrubbing units with high-pressure fans and ATEX certification. By steam regeneration of the loaded activated carbon, service lives up to 5 years are achieved, which save enormous operating costs. The complete plant technology, starting from the vacuuming of the vehicles to the chimney, the container and plant technology with nitrogen flooding, control system and gas warning center comes from a single source at Klose.
