Biomass boilers are heating systems that use organic materials, such as wood pellets, wood chips, or agricultural waste, to generate heat for buildings or industrial processes. These boilers operate similarly to conventional boilers, but instead of burning fossil fuels like oil or gas, they burn biomass materials.
Biomass boilers are an environmentally friendly option because they use renewable organic materials as fuel and help reduce dependence on fossil fuels.
Biomass boilers offer several benefits, both practical and environmental. These include:
Biomass boilers should be considered by a range of industries including:
If you can answer yes, to at least some of these questions – a Biomass Boiler could be a good option for your business.
Overall, biomass boilers offer a versatile and environmentally friendly heating solution for a wide range of industries, helping to reduce reliance on fossil fuels, lower energy costs, and limit the impacts on our environment.
If you’re interested in installing a biomass boiler for your plant or want to put in place a regular maintenance plan to ensure you maintain optimal efficiency, then give the EAS team a call today on 07 834 0505.

Motor Control Centres are the nerve centre of industrial automation and electrical distribution systems ensuring seamless operation of machinery and equipment in industrial and commercial environments.
A Motor Control Centre (MCC) is an assembly of one or more enclosed sections each containing components such as circuit breakers, contactors, overload relays and other components that help manage the power distribution, switching and protection of the electric motors in your system.
Benefits of Motor Control Centres (MCCs):
– Efficient power management
MCCs can include energy monitoring and management features to reduce energy consumption and improve motor performance – all contributing to overall energy efficienty and cost savings for your plant.
– Reduced down time through improved monitoring & maintenance
The modular design of MCCS makes it easier to access individual motor starters and components, simplifying maintenance tasks and reducing downtime. MCCs can also be equipped with advanced monitoring and diagnostic features such as remote monitoring, fault detection and predictive maintenance capabilities which all help optimise motor performance and can identify issues before they lead to unplanned downtime.
– Safety and protection of the motors in your system
MCCs incorporate safety features such as circuit breakers, overload protections and interlocking mechanisms which all improve the safety of motor operations protecting both your people and your equipment from electrical hazards.
– Convenient and organised way of managing power distribution
MCCs provide a centralised location for managing multiple motors, saving valuable floor space and making it easier for operators to monitor and manage motor operations from a single point.
Maintenance
To keep your MCC in peak condition, regular maintenance is essential. This should include:
– Inspections:
Regular visual inspections should be done to check for signs of damage, overheating, losse connection or corrosion of MCC components including motor starters, circuit breakers, wiring, busbars an insulation.
– Testing & Calibration:
Protective devices such as overload relays and circuit breakers should be tested and calibrated to ensure they will operate when needed.
– Connections:
Electrical connections should be checked periodically to ensure they are secure and free of corrosion. Loose connections can lead to overheating and electrical faults.
– Cleaning:
It is essential that the MCC enclosure and components are kept clean and free of dust to ensure all equipment operates at peak performance.
– Cooling Systems:
If your MCC is equipped with a ventialtion or cooling system then the fans, filters and airlow pathways should be checked to ensure proper ventialtion and cooling of the MCC components.
Motor Control Centres offer a complete solution for motor control and power distribution, combining convenience, safety, and efficiency for your plant.
If you’d like to investigate a MCC solution for your plant or put in place a regular maintenance programme for an existing MCC, get in touch with the EAS team today on 07 834 0505.

A: A cold spell.
Circuit breakers are automatically operated electrical switches designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.
The basic function of a circuit breaker is to interrupt the current flow when a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
Circuit Breakers play a critical role in protecting expensive equipment in your plant. However, they can go long periods without activation, so it is essential that they are regularly maintained and tested. If they fail to activate when needed it could have catastrophic consequences for your staff and plant if an arc flash were to occur and would result in extensive damage to your plant’s electrical systems.
Primary & Secondary injection testing of your circuit breakers should be included as part of your Preventative Maintenance plan to ensure their reliability and safety.
Primary Injection Testing vs Secondary Injection Testing
Primary Injection Testing injects a multiple of the fault rated current of the breaker through the breaker to measure the trip time.
Secondary Injection Testing injects a ratio of the fault rated current directly into the trip unit and measures how long the breaker takes to trip.
The primary tests of the breaker are closer to a real-world scenario while secondary tests the timing and functioning of the trip unit.
Primary injection testing is usually the preferred test method as it tests the entire circuit including the current sensors, wiring and the current conduction path in the circuit breaker as part of the test. However, it is also more expensive, so is generally conducted at commissioning and on circuit breakers that are part of a critical process or engineered safety system. Other than trip testing other tests that can be conducted as part of your primary injection testing include:
– Power Transformers (Through Faults)
– Relay Testing
– Bus-work, Switchgear and HV Breakers
– Low voltage breakers
– Switchgear Testing
– Heat runs
– Stability tests
– Loose Connections
– Core Identification
