Day-Impex Dilvac Dry Ice Maker

The Day-Impex DILVAC Portable Dry Ice Maker is the fastest way of providing a block of dry ice to your lab. 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.

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, and turn on the tap. Remember, it has to be a liquid cylinder with an internal siphon.

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

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

2. When block is made, turn off gas on cylinder; unclip lid and sides of unit

3. Remove block. Gloves must be worn. Replace sides and lid of the unit to instantly make another block if required

Use dry ice in: Hospitals, research labs, tissue preservation, food preservation, specimen transportation, Recreational purposes.

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

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 60kg/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. 1kg.
