Cool53 SmartLift

The Cool53 SmartLift combines the high insulation performance with the highest convenience possible and lowest height restriction (170mm). Available in different versions. 

The fixed soft-wall bulkhead can be repositioned throughout the entire refrigerated trailer/reefer when it is in a 45° position. This reduces the size of the cooled compartment (less fuel consumption) and keeps the cooled air in during loading and unloading. Simply fold the integrated wings on both sides to the inside to open the entire separation wall.

Cool53 SmartLift versions

Our Cool53 SmartLift comes in 2 different versions. Depending on the size of the cooled compartment(s) we offer our Cool53 SmartLift as:


Full width of vehicle

Cool53 SmartLift 1

2D 1/2-1/2

Evenly split in middle

Cool53 SmartLift 1/2-1/2
IsoLok SmartLift system


The SmartLift system on both sides with steel coil springs works in accordance with LoadLok 3061 or 3062 J-Track. This system allows the bulkhead to be easily and quickly repositioned over the length of the trailer. When the bulkhead is in parking or operating position, the balancers will lock automatically for safety during transport.

Your ultimate solution?

The Cool53 SmartLift is ideal in situations when the temperature difference between both compartments is more than 20° Celsius. Also, when convenience in operating is required, for example, with multiple stops during the day (multi-drop distribution). A fixed solution will give the advantage of quickly rescaling the cooled compartment and prevents cooled air from escaping.

Closed-Cell Foam Technology (CFT)

The outstanding insulation performance and usability is due to our unique closed cell cross linked foam technology. The foam is high impact resistant and does not absorb any water, ideal in a humid environment. The foam is wrapped in a thick and strong outer skin of PVC. Making it the most durable and economic bulkhead in the market! The insulation performance is measured in K-value (W/ m2 K). IsoLok solutions with our CFT technology offer the highest K-value performance in its product segment. Significantly better value for money than bulkheads of e.g. OEM’s or others. Each of our IsoLok solutions have been tested by an independent research center Wageningen University of Research (WUR NL) and are expressed in a K value for thermal conductivity. The K-value expresses the amount of heat that passes through over time per m² and per degree of temperature difference between one side of a wall and the other. The lower the K value, the less heat is lost and therefore the better the insulating performance.


The unique SmartLift balancer system allows the bulkhead to open/close and to reposition the wall in the vehicle. With almost no effort the operator can reposition the wall throughout the vehicle. The SmartLift system has the lowest height restriction in the market: 110 mm. A unique feature when you want to maximise the capacity of your vehicle.

It is equipped with an automatic locking system to prevent any movement during transport. Inside the balancer there is a steel coil spring – completely free of maintenance! The balancer slides in LoadLok J-Track (available in different material finishes).

Higher efficiency with multiple temperature zones

IsoLok Multitemp solutions help to rescale the conditioned compartment to the minimum possible (even for partial loads). With market-leading insulation performance and compartment closure, these solutions are able to save users over 40% on energy consumption*. The reduced size of the conditioned compartment enables transport companies to transport dry or cooled products in the remaining space, increasing flexibility and load efficiency and thus increase profit in the cold chain!

PIEK Certified for night deliveries

Several IsoLok solutions have been approved and certified according to PIEK standards. With this certificate the bulkhead is suitable for distribution during night-time in city centres!

Governments defined standards for noise emission during loading and unloading during night-time deliveries. A PIEK certificate is issued for vehicles and equipment operating under 60dB(A) which will be suitable for use in night-time deliveries without causing noise disturbance. Check the PIEK certificate in the download section of the product to see if PIEK is applicable.

ATP and HACCP compliant

The ATP, (Accord Transport Perissable) and HACCP (Hazard Analysis and Critical Control Points) set strict regulations for the transport of perishable goods. 

The Cool and Frigo Series are compliant to this norm 1

Tailored to any vehicle or application

With market demands varying greatly, our product offering goes far beyond its standard solutions. If the end-user wishes specific requirements which are not in the product line, we are able to customise or develop custom-designed solutions, tailored to the specific needs of its customers. 

We have developed and produced specific solutions for Meat, Pharma, Supermarkets, Retail and Restaurants. And not just for reefers, also for Light Commercial Vehicles (Sprinters etc.) Multiple folding, integrated doors, wings, or a specific parking solution?
