Do you want to increase your profit in the cold chain? With our extensive IsoLok Cool Series we are able to provide the ultimate solution for any type of transport. These solutions offer the highest insulation performance in transporting a combination of frozen, cooled and/or dry products in one vehicle. Rescaling the cooled compartment increases the efficiency in terms of fuel consumption and prevents cooled air from escaping from the vehicle during loading and unloading!

Temperature Controlled Transport

Are you a transport company who would like to increase efficiency? Or a bodybuilder who’s looking for the most efficient Multitemp solution for his customer?

Increasing profit in the cold chain

We offer a diverse range of Clever Panel Technology (CPT) Frigo Series solutions and Closed-Cell Foam Technology (CFT) Cool Series solutions. Solutions that excel in insulation values, durability, and ergonomic performance combined with the lowest loading height restriction in the market.

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?
