Colloide designs and builds a variety of pumping systems for our clients, pumping anything from pure water through to heavy slurries. As a process engineering contractor, we will develop the package which is the best fit for the purpose. It will have one or more pumps at the core, but with ancillary equipment designed into the system. Variances include: A variety of pump types such as submersible/dry well end suction/progressive cavity/ vertical multistage etc. Pipework in stainless steel, ductile iron, galvanized mild steel, epoxy coated steel, UPVC, ABS, MDPE… Control panels in a range of standards with optional data logging, alarms, remote monitoring, etc. Level controls such as ultrasonic level contollers, float switches, pressure transducers.

Colloide designs and builds customised energy centres which generate heat which can then be distributed to buildings or district heat networks. We can also incorporate CHP units within the energy centre, providing electricity along with heat and a low carbon heat and power solution. Our energy centres are often designed to have more than one energy source, allowing the plant operator to vary the energy sources in relation to the energy demand and the best value for money at a given time. The energy sources may include: Gas fired boilers. Biomass boilers. Heat pump. Oil fired boilers. Combined Heat and Power (CHP) unit Our centres are engineered to include the energy sources, thermal stores, instrumentation, control systems, pumping and pipework network – building in as much flexibility as possible so that the plant can be operated as efficiently as possible.

Colloide designs and installs heat pump systems. The heat pump extracts the energy at the source temperature and then raises the temperature to a useable level. A heat exchanger is used to extract the heat from the circuit at this point, with the now cooled medium being returned to the source where it is reheating. Reversible heat pumps can also be used in cooling function which can be important in the summer months. The heat pump works as part of a closed loop, operating between the heat source and the building where it is to be used. Heat sources include air, water, ground and waste heat. The higher the temperature and larger the size of the source energy, the better it is for providing energy. Colloide designs its systems to maximise the return from the heat source. Our heat pumps include a control system. The control system will vary depending on the plant, but is always designed to give our customers full control, including the ability to monitor performance remotely.

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.

What is Anaerobic Digestion? Anaerobic Digestion is a natural biological process that can be used to generate renewable energy and manage waste. The process takes place in an oxygen-free digester, where micro-organisms convert organic material such as food waste, slurries and crop residues into: Biogas Biogas is a mixture of biomethane gas and carbon dioxide. The biogas can be used directly in CHP engines to produce renewable heat and power, or it can be burned to produce heat only. Alternatively, biomethane can be produced by removing the carbon dioxide from the biogas. The biomethane has many valuable uses. It can be injected into the gas grid as a renewable replacement for natural gas or it can be used as vehicle fuel. Digestate The by-product from the AD process is called ‘digestate’. It is rich in valuable plant nutrients such as nitrogen and potassium, and can be used as a renewable fertiliser/soil conditioner.
