Dobles Do the Double with Hubbard Twin Evaporators

Cornwall's leading foodservice supplier, St Agnes based Doble Quality Foods has added another new Iveco Daily 3.5 tonne twin compartment refrigerated vehicle fitted with a Hubbard 520 Alpha fridge unit to its 11 strong fleet servicing the West Country. Over 25% of Doble’s transport fleet now feature Hubbard refrigeration units.

Doble Quality Foods is an independent, family owned company that has been trading for over 60 years and can trace its roots back to Llywelyn Doble whose son Ian is now Managing Director. Doble Quality Foods employs 24 staff supplying the public sector, independent hospitality and leisure outlets and brewery chains.

Transport Manager, Jerry Phillips says: "Hubbard are well known to Doble Quality Foods, we have been working with the Hubbard Technical team for almost a decade and we were one of the first companies in the West Country to use their Eutectic beam systems. So, when we were looking for another twin compartment vehicle for our fleet with a specification that included an ambient of +3ºC for the chilled compartment and -25ºC for the frozen compartment with a fast pulldown and the performance to accommodate up to 15 door openings per delivery run, The Hubbard 520 Alpha combined with a new ATP certified refrigerated body was the perfect choice”. He continues: “As a customer focused company the ability to deliver a quality product is absolutely essential to us, as is economy and efficiency – in our experience Hubbard deliver on all counts".

The Hubbard 520 Alpha solution chosen by Doble Quality Foods is a split system designed to operate in medium to large truck box bodies that are suitably insulated for fresh or frozen produce transportation.

The refrigeration system is driven using a compressor that is mounted within the engine compartment and belt driven from the vehicle engine crankshaft. When the vehicle's engine is running and the thermostat calls for cooling an electro-magnetic clutch on the compressor is engaged enabling the unit to provide refrigeration. A semi-hermetic compressor powers the refrigeration system on mains standby.

The 520 Alpha uses environmentally friendly R404a refrigerant and is suitable for temperatures down to -25ºc. The system is operated by an easy to use in-cab digital controller that is fully programmable and provides constant temperature readout.

Doble Quality Food’s 520 Alpha multi-temperature split system comprised a condenser and a twin fan evaporator, with electric standby and an in-cab digital controller.
