Need some help? Stuck for an answer?

Here, we have tried to answer some of the most frequently asked questions relevant to the Marshall Fleet Solutions business. We are here to help and provide you with the answers.

Take a look through our FAQ’s:

Transport Refrigeration – General

Q. What information do you require to specify a new Thermo King refrigeration system?

A. Typical questions we would ask to ensure that the system can carry your designated products at the correct temperature are:

What type of products do you transport? Are they frozen or chilled? How many door openings per hour? What’s the length of a normal journey?

Choice is everything.

With refrigerated transport, there are so many parameters that affect the performance of a refrigeration system. The more knowledge we have about your transport operation, the more accurate specification of system can be recommended by our skilled experts.

We have produced an easy-to-complete, step-by-step information document that asks all the relevant questions that will enable us to specify the optimum fridge system for your vehicles.

Simply fill in our on-line, easy-to-complete ‘Choices’ document here and we will do the rest. Alternatively, call us on 0800 731 1685 and we will talk you through the questions.

We will then review your requirements and contact you by return with our recommendations.

Transport Refrigeration – LCV’s

Q. Are there preventative measures we can take so the refrigeration system works to its best ability in the summer?

A. Keep door openings to a minimum and turn unit off whilst loading the freezer and chiller.

Q. Our refrigeration system keeps icing up in the back, what can I do?

A. Turn the unit off whilst loading the freezer and chiller.

Do not pressure washer/hose down inside chiller or freezer.

Defrost unit on return visits to store and after loading.

Q. What is the best practise for running our transport refrigeration systems on standby?

A. Ensure the power is turned off at the wall.

Inspect the lead for damage and keep the Standby leads tidy and off the floor (to avoid water and damage)

Plug the lead into the socket on the van.

Turn the fridge on and check the temperature settings.

Transport Refrigeration – F-Gas Refrigerant Update

Q. What’s the latest position with R404A refrigerant and the new F-Gas regulations?

A. The refrigerant most widely used in Thermo King refrigeration units is R404A, however changes to the F-Gas regulations has brought about the need for Thermo King and Marshall Fleet Solutions to change their refrigerant usage policy.

TK has now developed all its new fridge units to run on R452A refrigerant, which is widely available and meets all future legislation.

For a full explanation of the impact of the new F-Gas legislation either call us on 0800 7311 685 or simply download our latest F-Gas Update leaflet here.

Q. Can we switch to the new R452A refrigerant on our current vehicles that have TK units specified with R404A?

A. Yes you can, quite easily. With the development of R 452A refrigerant in new TK units, with its lower GWP, MFS is now offering R452A as a replacement (drop-in/conversion) on existing customer TK fridge units. This is a relatively straightforward conversion to the fridge unit, supported by Thermo King technology and MFS‘s F-Gas compliant engineers, which can be carried out in conjunction with schedule services and/or refrigerant leak checks.

If you wish to proceed with R452A conversions for those vehicles currently operating with TK units running on R404A either call us on 0800 7311 685 or simply download our ‘Changing the Gas’ leaflet here for more information.

Q. Does MFS have an overall environmental policy?

A. MFS is committed to the environmental principles of responsible stewardship and sustainability. If you click here you can download the latest MFS Environmental Policy Statement.

Transport Refrigeration – Calibration

Q – Do I need to have my fridge system calibrated annually by law ?

A – No this is not a legal requirement – but you will have to demonstrate due diligence that your loads have been transported at the correct temperature during transit. MFS will calibrate the refrigeration equipment at 0 degrees C annually, as standard.

Q – I carry Pharmaceutical Products. What are my calibration requirements?

A – An annual calibration is normally suitable at 0 degrees C but, dependant on your own internal processes, you may require additional temperature ranges and checks. We call these a Temperature Performance Certificate, as they are testing the capability of the whole refrigerated body as well as the refrigeration unit. Contact MFS for Pharma assistance.

Q – To what standard does Marshall use for on there temperature test equipment ?

A – Marshall tests all engineers temperature testing equipment annually to UKAS Standards.

Transport Refrigeration – Connectivity

Q – Is TouchLog Datalogger compatible with third party telematics connectivity?

A – Yes, it is. Contact your MFS representative for more detailed information.

Q – Does TouchLog Datalogger incorporate an integrated printer for Point of Delivery temperature ticket?

A – It incorporates a high-speed thermal printer, printing tabular or graphical data and can also be downloaded to .PDF or .TXT files via a USB device.

Q – Is TouchLog Datalogger certified to EN12830 and WELMEC 7.2 standards?

A – Yes, it does meet those standards and its accuracy is 0.5 degrees C.

Q – What is the memory capacity of TouchLog Datalogger?

A – 8Mb, allowing for on board minimum storage of 12 months data.

Tail Lifts

Q. Is a Statutory Thorough Examination (STE) a legal requirement?

A. Yes It is a legal requirement that you have a current report of thorough examination (STE) for the tail lifts that are fitted to your vehicles.

Q. How often should a Statutory Thorough Examination (STE) be carried out?

A. Every 6 months if the lift in question carries any passengers at any time, this also includes animals. Every 12 months for any lift that can be proved does not ever carry passengers.

Q. What sort of Tail Lift do I need?

A. This depends on what operation and environment it is to be used in, Marshall Fleet Solutions can work with customers to advise which lift would be best suited. Just call 0800 7311 685 and request a call back or email

Q. How often does a lift require a Weight test and is it a legal requirement?

A. Once the lift has been fitted and a weight test carried out before first use, then legally it does not require another test, unless it has a structural repair.

However, it is recommended that a weight test is carried out annually to highlight any problems or issues that may be occurring un-noticed without weight being applied.

Q. At what intervals does my tail lift require routine servicing?

A.  It all depends on the usage and environment that it is being used in. Always remember that sometimes very occasional use can be just as harmful to the lift as very heavy use. Again, at Marshall Tail Lift, we can advise on specific customer needs.

Q. What is the best practice to wash a Palfinger column tail lift?

A. Download the Palfinger Lubrication Guide (here).

General rules are:
(1) Do not use aggressive cleaners
(2) Do not wash out the columns
(3) Re-lube where required or request technical assistance
(4) ONLY use the Original Equipment Manufacturer Guidelines on the type and location to add the lubrication.
