Transport refrigeration services

MWL maintains and provides engineering advice on all types and brands of refrigerated transport systems. These range from small truck home delivery fleets and large trucks used for multi-drop food distribution to trailer fleets in the retail and pharmaceutical sectors.

Many client’s fleets have different types and makes of refrigeration units and vehicles of different ages, sizes and configurations. Being independent, we work with all types and brands of units refrigeration and vehicles, and always provide impartial, expert advice.

Our solutions and options are bespoke for each client, based on their individual requirements and challenges. The company has the best systems, knowledge and experience to provide exceptional service and solutions.

Greener technology

Innovative and entrepreneurial, we promote greener refrigeration technology while also working with traditional refrigeration equipment.

We advise and help clients practically in making the gradual transition to cleaner technology and electrification of refrigeration systems over time. 

MWL has been a service provider for FRIGOBLOCK refrigeration systems for 30 years and is a sales and service dealer. FRIGOBLOCK systems efficiently generate electrical power to drive the refrigeration unit by using an alternator connected to the main truck engine which complies with the latest emission legislation. In contrast, traditional heavy truck refrigeration systems rely on an additional industrial diesel engine to power the refrigeration system. Traditional units need their own fuel supply and do not conform to the latest emission standards for modern truck engines.

FRIGOBLOCK systems are cleaner, more efficient, save significant fuel costs and comply with latest clean air standards and vehicle standing time restrictions. They have lower maintenance costs, very powerful, rapid temperature pull down and are a good return on investment.

Servicing backed with years of experience, training and accreditations

We are independent specialists in servicing and maintaining all types and brands of commercial and industrial heating, cooling and ventilation systems. Along with expert advice and support from highly skilled, qualified and experienced engineers, we use quality components and equipment to meet all our clients’ needs. We work across all types of properties, sector and sizes. From offices, retail properties and coldrooms to warehouses, factories and manufacturing environments, we have a hassle-free maintenance package to give every type of business, large and small, peace of mind and the best solutions.

Transport refrigeration FAQs

What is transportation refrigeration?

Refrigerated transport is a way of transporting goods in specially designed, temperature-controlled vehicles.

Perishable goods such as food, pharmaceuticals, flowers and medical products transported in vans, lorries and trailers, are required to be kept at a certain temperature to prevent them from deteriorating and losing value.

Equipment installed to these vehicles to control the temperature are called transport refrigeration systems. Their function is to remove unwanted heat from the storage area to maintain a set temperature. For some frozen products this could be as low as -25 to -30 degrees centigrade.

What is a transport refrigeration unit/TRU?

Known as TRUs, Transport Refrigeration Units are climate-controlled containers that keep the cargo at a regulated temperature, whether the truck engine is running or not. Traditionally, most TRUs have been diesel-powered but due to air quality concerns and the green agenda, hybrid and electric options such as FRIGOBLOCK are growing in popularity.

How do refrigerated vehicles work?

In a standard refrigeration system, the aim is to remove heat from the air in the space surrounding the stored product and then release it outside of the storage space. This is achieved by causing a liquid refrigerant to change state from a liquid to a gas within the storage space, and thereby absorbing heat from the air in the space during this process.

The absorbed heat is then carried within the gas to the outside of the storage space, where it is condensed back to a liquid and in the process gives up its heat to the atmosphere. This cycle is repeated continuously to achieve the desired temperature within the storage space.

What can transport refrigeration be used for?

Most transport refrigeration systems are used for the carriage of frozen or chilled food and beverage products. An important feature of most transport refrigeration systems is the ability to operate at a range of temperature levels for certain products. See the most conventional temperature ranges below.

Refrigerated transport temperatures

Different products demand different temperatures while in transit. An optimal transport temperature is product-specific calling for a wide variety of temperature settings, but five temperature standards are among the most common:

  • Deep freeze: -25C to -30C is the coldest temperature range that most conventional refrigerated units can maintain – usually for seafood and ice cream.
  • Frozen: -10C to -20C – used for frozen meat and bakery products.
  • Chilled: 2C to 4C – the standard temperature for refrigerated transport – used for fruit, veg and fresh meat.
  • Pharmaceutical: 2C to 8C.
  • Banana: (12C to 14C) Believe it or not, as one the world’s most produced fruit, the banana has its very own temperature setting to control ripening during shipping. Other tropical fruits are best transported in this range too.
What is transport refrigeration mechanic?

In order to keep machinery working as efficiently as possible regular maintenance is very important. The cargo carried in refrigerated vehicles is often very high value and it is crucial to ensure the equipment is working correctly to protect the product on board.

A transport refrigeration engineer will install and commission systems on vehicles and trailers, provide regular servicing and respond to breakdowns. It’s an important role in keeping the country’s supply moving.
