About Dilvac Dry Ice Maker

  • Compact and lightweight
  • Requires no electric power
  • Safe and simple to use
  • Converts liquid carbon dioxide into a block of dry ice in less than 60 seconds
  • Two block sizes of dry ice can be made - 0.8kg and 0.5kg

The 'DILVAC' Portable Dry Ice Maker is the fastest way of providing a block of Dry-Ice to your lab. Most importantly, it is always there in the lab to give you immediate access to Dry Ice whenever you may 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. 1 Kg in weight in not much over 1 minute, and all you have to do is connect the unit to a cylinder of CO2, and turn on the tap. Remember, it has to be a LIQUID cylinder with an internal siphon.

Dry Ice Maker - How it works

The Dilvac Dry Ice Maker is as simple to use as 1,2,3.

Dry Ice maker steps

The Dilvac Dry ice maker comes with easy to follow operating instructions. Read below, for brief instructions on how to use:

  • Connect unit to Liquid CO2 cylinder and turn on.
  • Monitor flow of liquid by means of pressure gauge provided.
  • When 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.

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 110mm x 180mm and weighs approx. 1 Kg.

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


Ideal Applications

  • Hospitals
  • Research Labs
  • Tissue Preservation
  • Specimen transportation
  • Recreational purposes
  • Food preservation

Does this Dry Ice Maker create dry ice pellets or flakes?

The dry ice maker makes blocks only, Dimensions of block - 80mm x 110mm x 180mm Dimensions of box - 160mm x 160mm x 225mm, Weight of block - 1Kg +/- 10%

Dilvac Dry Ice Maker Specifications

Dimensions of block - 80mm x 110mm x 180mm
Dimensions of box - 160mm x 160mm x 225mm
Weight of block - 1Kg 10%
Yield from 34Kg Cylinder - 5 - 6 blocks*

*A 34Kg cylinder at room temperature will contain approx. 30Kg's 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 approx. 1/3 more blocks may be produced.

What is cryogenic equipment used for?


Cryogenic equipment is used when you need to operate at extremely low temperatures – the acceptable division between simple refrigeration and cryogenics is -180 degrees Celsius. Typical equipment used in cryogenic applications includes containers, pressure vessels, cold traps, purifiers and piping.


Among the most commonly used cryogenic equipment is a specialised container known as a Dewar flask. (insert link to Divlac Dewar Flask page) Named after its inventor, Scot ‘Sir James Dewar’. This famous piece of cryogenic equipment comprises of a holding chamber within near vacuum, and the Dewar flask prevents the transmission of heat from its contents through the processes of conduction and convection. Dewar flasks also reduce the transmission of heat through the process of radiation, by using selected reflective coatings for various surfaces within the flask. In cryogenic applications, Dewar flasks are typically used as holding tanks for the selected cryogenic liquid.


How does cryogenic equipment work?


Proper insulation is often key to the effectiveness of cryogenic components, as it ensures that temperature levels are maintained within the equipment. Similarly, insulation protects cryogenic equipment users from dangerous temperatures and materials during handling. Of the liquids regularly used in cryogenic operations, nitrogen and helium are the most common; liquid helium in particular allows for extremely low temperatures. Also important to most cryogenic equipment, especially valves, gages and piping systems, is the pressure rating of the unit; the majority of cryogenic systems have specific pressure requirements in order to retain fixed temperatures.
