Watkins Hire's specialist temperature control product range can effectively assist with the processes involved in both anaerobic and aerobic digestion.
Anaerobic digestion is a collection of processes by which microorganisms break down the biodegradable material in the absence of oxygen. Anaerobic digestion is becoming the preferred process used for industrial purposes to manage waste and to produce fuels. The process is widely used as a source of renewable energy, bio gas is produced and can be used directly as fuel, upgraded to natural gas-quality bio-methane and digestate can be produced and used as a fertiliser.
Watkins Hire's cooling and heating range is used to assist with these processes.
When a well known energy company required temporary cooling to assist with their anaerobic digestion process, Watkins Hire Limited were their first call.
Their on site digester tanks needed cooling as the high ambient temperatures were affecting the pasteurisation process. Watkins Hire utilised its KwikCHILL 170 which is a 170kW fluid chiller unit capable of cooling fluid down to -12 degrees. The chiller was connected directly on to the onsite water circuit to enable the process to be controlled and temperatures to be reduced gradually by 1 degree a day to ensure thermal shock did not affect the process.
Watkins Hire Specialist Engineers configured the cooling equipment to run as two separate circuits as the sites application was at a temperature too high for standard cooling. A plate heat exchanger and secondary booster pump was used as part of the Watkins cooling package to allow the chiller to complete the application required without effecting the operation of the unit.
As the market leader Watkins Hire have many years of experience in providing complete rental solutions for critical temperature control requirements across all industry sectors and are the only hire company with this complete and diverse product offering.
