The DILVAC Portable Dry Ice Maker is the fastest way of providing a block of dry ice to your laboratory.

It is compact and lightweight, requires no electric power, and is safe and simple to use. Most importantly, it is always there in the lab to give you immediate access to dry ice when you need it.

The economy of having your dry ice ‘on tap’ can provide considerable financial savings over a relatively short period as the cost of having dry ice delivered to your lab can be prohibitive.

The DILVAC Portable Dry Ice Maker produces a block of approx. 1kg in weight in less than 2 minutes, and all you have to do is connect the unit to a cylinder of CO2 (with an internal siphon), and unscrew the valve. 


Hospitals, research laboratories, tissue preservation, food preservation, specimen transportation, recreational purposes.


Gaseous CO2 vapours can cause suffocation, so use the unit only in well-ventilated areas. Also, use the unit only on a level supporting surface. Never allow the unit to hang from the feed hose. 

Do not handle dry ice without gloves. It is very cold (circa -80°C).


Block Dimensions: 80 mm x 110 mm x 180 mm
Box Dimensions: 160 mm x 160 mm x 225 mm
Block Weight: 1 kg ± 10%
Yield from 34 kg Cylinder:  5 – 6 blocks*

The DILVAC Portable Dry Ice Maker works on the principle of adiabatic expansion (the Joule-Thompson effect).

The liquid CO2 in the cylinder is at a pressure greater than 60 kg/cm2, so when it is released into the unit, which is at atmospheric pressure, the liquid CO2 vaporises and expands. As a result of this expansion, the liquid changes to snow and is compacted into a block within the unit. The block measures 80mm x 110 mm x 180 mm and weighs approx. 1 kg.

*A 34 kg cylinder at room temperature will contain approx. 30 kg of useable liquid CO2, the balance is vapour, which does not convert to solid dry ice. Yield can be appreciably increased at lower ambient temperatures, i.e. @ 5°C approx. 1/3 more blocks may be produced.

How Does It Work?

The unit comes with easy to follow operating instructions. Briefly, this is how it works:

  • Connect unit to liquid CO2 cylinder and turn on. Monitor flow of liquid by means of pressure gauge provided
  • When the block is made, turn off ‘gas on’ cylinder; unclip lid and sides of unit
  • Remove block. Gloves must be worn. Replace sides and lid of unit to instantly make another block if required.
