Why should I run a manual defrost?

  • September 23, 2019 /

Why does ice-build up?

Even at set points which are at an ambient temperature, in order to keep temperature regulated and controlled, the temperature at the evaporator is likely to be much colder.

Water particles are present in the air, and so the amount of water present in the unit increases with every door opening. This water when mixed with cold air then creates ice build-up on the units. If there are more door openings then ice is more likely to build up, therefore you are likely to need to run a defrost or tempering cycle more often.

Frozen evaporator coil

How does ice affect the running of the unit?

Ice puts all components in the unit under more pressure and reduces cooling and operational efficiency. Due to the way ice forms, excessive build up can crush the evaporator coil. This means the unit is likely to breakdown, and can cause costly repairs, as well as leading to significant operational down-time.

What should I look out for? How do I look for it?

Although it seems obvious, look for any signs of ice on the unit. The most important places to check are the evaporator coil, this is inside the unit where the cold air comes from. In Blast Freezers this may be above a false ceiling, so please ensure that you use appropriate health and safety procedures to check this area, and don’t cause damage to the false ceiling. Ice can also build up on the floor, or walls of the unit, so ensure you check these areas also.

What should I do to solve the issue?

All of our units run an automatic defrost in their running cycle, however, these automatic defrosts are stopped when doors are opened. If interrupted the efficiency of the automatic defrosts are significantly reduced. This re-concurrence of interruptions over a period of time will eventually render the automatic defrost less efficient. Our units additionally come with manual defrost or tempering cycles which are able to be activated in order to remove this ice-build up.

If any ice is detected then you need to run additional manual defrost or tempering cycles.

Ensure that after the cycle all ice has melted, and the water has completely cleared from the drains. Depending on the amount of ice build-up, it may be necessary to run more than one additional manual defrost or temper for longer in order to clear all the ice and ensure all water has drained away. For very excessive ice, empty the unit and run at at least 8oc and ensure all water drains away.  If all ice and water hasn’t cleared then by running the unit again you are more likely to rebuild ice up again quicker.

We recommend that clients get to know their units, understanding when automatic defrost are run and how long they run for. Keeping a chart on the wall can lend a hand to ensuring that during automatic defrosts the doors aren’t opened. We would also recommend that units are cleared out and a full manual defrost s run once a month.

Daloon thrives from solution driven partnership with Blue Cube

  • August 27, 2019 /

When frozen food producer, Daloon, needed to update their cold storage needs, they were considering numerous companies, and at this time received a call from Blue Cube Portable Cold Stores (PCS) introducing their services.

Lisa, UK Sales manager, explains, “I met with Andy from Daloon and he explained they were looking for a facility to increase capacity and ease product movement on site.

"They were facing challenges with working at heights, and so it was vital to find a solution which resolved this. We’re very transparent as a company and try to work in partnership with our clients rather as suppliers, and so we gave our best cost-effective price on first quotation for a solution that worked for Daloon.”

The cooperative working relationship was a key driver of the decision making process according to Andy Reed, GoodLife Foods Interim Engineering Manager, “I’ve been really happy with how Blue Cube have worked with us to find a solution that fit our business needs. We found the process very straightforward and customer friendly.

“The speed that Blue Cube work at really sets them apart from their competitors. They focused on finding a solution to our particular needs which was cost-effective, and their customer service throughout the entire process was excellent. The relationship with UK Sales Manager, Lisa, has been spot on. Everything I asked of her she delivered on, I couldn’t fault the whole process.

“The units arrived on time and we were given plenty of information to get the best use out of them. I couldn’t fault the service from beginning to end. I’d use Blue Cube again without a shadow of a doubt.”

Keep your unit running smoothly this summer

  • July 22, 2019 /

​With a summer scorcher predicted, ​and temperatures in the 30s expected, your unit will be under increased pressure to maintain and reduce temperatures. To avoid potentially costly call-outs follow Blue Cube's summer tips below: 

  • ​Check condenser coils at the back of the unit aren't blocked or dirty. This may prevent enough air being circulated around the unit causing parts to overheat and not work to their optimum performance.
  • ​Check there is no ice build up on the evaporator inside the unit. The area in which cold air is circulated into the unit can become built up with ice, which becomes a blockage to the cold air circulating keeping products cold. Running regular defrosts, and ensuring that any water is draining freely, will help to reduce any ice building up in your unit.
  • ​Make sure to try and reduce door opening as much as possible. Doors openings allows warm external air to enter, meaning the unit has to work harder to cool more air. Although some door openings can't be avoided to add and remove stock, try and keep these to a minimum in warm weather.
  • ​Ensure strip curtains provided ​are still in place. Although they can seem like a pain to work around, strip curtains are vital in helping to retain cool air within the unit during door openings. They also go some way to blocking warm air from entering the unit.
  • In warmer weather it's especially important to make sure ​you follow the 'Daily Operation Checks'. These are provided to you when you first receive the unit, and many of our units have them written on them with stickers. But if you would like this sent to you then please don't hesitate to contact us.

​​For any further advice about how to prepare for the warm weather please don't hesitate to contact our ​Service Department on 0333 3202 620.​

Cornish pasty producer increases frozen capacity

  • July 10, 2018 /

Cornish Pasty

Award winning bakery and Cornish pasty producer, Prima Bakeries has increased its frozen capacity through acquisition of a portable cold store from Blue Cube Portable Cold Stores.

The bakery, based at Redruth in the heart of Cornwall took delivery of the cold store in June following a requirement for additional frozen capacity.  Using a portable cold store meant capacity could be increased quickly and within budget.

Prima Bakeries has been baking delicious Cornish Pasties, bread, cake, confectionery and savoury products in the heart of Cornwall for over thirty years.  The bakery has a retail range for shops and convenience stores and a foodservice range for cafes, hotels and restaurants. The bakery is also well known for its ‘Pasties by Post’ service, delivering direct to consumers.

Blue Cube – one of the UK’s leading providers of rental temperature controlled storage solutions for the food and logistics industries – has supplied Prima Bakeries with the largest unit from the portable range.  This gave the site an additional frozen capacity of 37 pallets to cope with 20% growth.

Blue Cube worked closely with Mark Norton, Managing Director of Prima Bakeries to find the best possible solution for the site.  From the initial enquiry in November 2017 right through to delivery in June 2018 all options were considered to ensure we supplied the right product.  Although Blue Cube’s core business is rental, a unit was sold from the fleet to support the customer’s requirements.

It was a challenging site due to ground levels so Blue Cube offered a full package deal.  This included provision for groundwork’s and levelling as part of the sale.

To ensure the unit was future proofed, Blue Cube went one step further and replaced the refrigerant from R404A to R452A.  R452A has a GWP of 2140 – a little over half that of R404A.

Mark Norton, Managing Director said “Blue Cube have delivered consistently good service, right from the start of this process through to procurement of equipment, delivery and aftercare”

“To ensure Prima Bakeries kept in line with ever changing F-Gas regulations it was important that we considered the GWP impact of the cold store.  Blue Cube were on hand to offer advice and replaced the refrigerant which will keep us compliant for years to come”
