A herbal remedy

Herb specialist Scotherbs has moved into a new state-of-the-art facility in Longforgan, near Dundee, which features the latest environmental control technology from Mitsubishi Electric fitted with the expertise of Carlisle Refrigeration.

The purpose-built factory enables Scotherbs to increase production rates of the extensive range of fresh, washed and prepared culinary herbs, whilst housing all processes into one building with improved energy efficiency. The building has a large temperature controlled area, plus a high care area with filtered air to F9
En779 standard. Both areas take advantage of the heat recovery capabilities of the Mitsubishi Electric City Multi VRF system.
“The biggest advantage of City Multi is the fact that it can provide cooling down to a preset point, which meets with our production requirements to ensure our products are kept in peak condition during the manufacturing process,” said Fiona Lamotte, Managing Director of Scotherbs, which is Scotland’s premier grower of fresh culinary herbs.
“Adding in heat recovery means that we are able to offset energy use from different parts of the building to provide the ideal environment for both our staff and our products in the most sustainable way possible.”
Scotherbs has been growing and sourcing fresh, washed and chopped culinary herbs, leaves and salads for supermarkets, wholesalers, the catering trade and discerning consumers for over 20 years and is now one of the UK’s largest suppliers.
Carlisle Refrigeration installed PEFY-P140VMH-E ducted units served by a PUHY-P300YGM-A outdoor unit, with four Lossnay heat recovery units. In addition, five DX refrigeration systems were installed for the chill storage rooms, and Carlisle Refrigeration fitted ventilation serving the office areas and the full site electrical installation, and a wireless temperature monitoring system.
“The system really benefits from the inclusion of the Lossnay units, which are incredibly efficient at extracting heating or cooling energy from outgoing air,” explained Campbell Wark from Carlisle Refrigeration. “This reduces the overall energy needed by the building’s systems which is important when you need to maintain such strict temperature control.”
