| 1. ON Coldry |
| What is Coldry ? |
| Solid form of Carbon Dioxide (CO2) is called Coldry . SICGIL produces Coldry in the form of blocks (of 5 / 8/ 10 / 12 kg sizes) and as pellets. The temperature of Coldry at atmospheric pressure is (-) 79°C. |
|
What are Pellets? |
| Pellets are very small particle of Coldry, resembling rice and measuring around 3 mm size. |
| Where Can I Buy Coldry Pellets? |
| Please visit Contact us page. |
| Are Coldry Pellets Better than Coldry Blocks? |
| Yes. Coldry pellets are far more efficient than blocks due to their compact strength than flakes cut or grated from a Coldry block. |
| How Should Coldry be Stored? |
In general, Coldry is not usually produced and stored; it is produced against firm customer order. It is highly recommended that you plan about your requirement and send your order. In this way, you can avoid storage loss.
However, in case you need to use Coldry at a distant locations or on holidays or during odd shift hours, then ensure that you carry sufficient quantities of Coldry in PUF insulated containers which would ensure very low transit loss of around 4 – 6% every day.
|
| Can I recycle Coldry Pellets ? |
| No. After hitting the surface, the Coldry pellets sublimes into CO2 vapour. |
| 2. ON Coldry BLASTING PROCESS |
| What is Coldry Blasting? |
| Coldry blasting is a latest blasting method which uses Coldry pellets / blocks in lieu of traditional blasting materials like glass, plastic, sand and water. As Coldry sublimes into atmosphere, only the cleaned dust / waste have to be disposed.
|
| Can I recycle Coldry Pellets ? |
| No. After hitting the surface, the Coldry pellets sublimes into CO2 vapour. |
| Does Coldry Blasting Cause Condensation? |
| While cleaning warm / hot surfaces condensation does not occur normally as the temperature will remain above the dew point. When cleaning is performed in cold locations, we recommend the use of heat lamps, fan heaters or heated compressed air.
|
| Does Coldry Blasting have any Environmental Consequences or Benefits? |
| While cleaning warm / hot surfaces condensation does not occur normally as the temperature will remain above the dew point. When cleaning is performed in cold locations, we recommend the use of heat lamps, fan heaters or heated compressed air.
|
| 3. ON Coldry BLASTING - DEMO & TRIALS |
| Is a Demonstration of IceBlast Machines Possible?
|
| Please contact TeamSICGIL which will be at your service from the moment you send your enquiry.
|
| Do I have to dismantle my Machine Before Coldry Blasting? |
| Not necessary to dismantle machinery or equipment to be cleaned by Coldry blasting process. |
| Can I use Coldry Blasting to Clean Hot Mould / Machinery in situ ? |
| Yes, you can. In fact, when the mould / machinery is hot, it would aid the cleaning.
|
| Does Coldry Blasting Damage the Underlying Surface?
|
| No. by adjusting the blasting pressure, depending upon the material to be treated, we can remove the coatings without damaging the underlying material itself. In fact, Coldry blasting can be used on easily-damaged materials like Chrominium nickel and soft aluminium.
|
| How Quickly can Various Objects/Materials be Cleaned?
|
| Type of coating and the underlying material, temperature of the machinery / mould to be treated, air volume decide the cleaning speed. You can undertake some trials before deciding on the right combination.
|
| Do I have to necessarily provide an External Compressed-air Source ?
|
| Yes. Our Coldry blast machine requires : Operating pressure – minimum 5 bar / maximum 16 bar; Compressed-air consumption – 3-11 m3/min. depending on nozzle combination.
|
| 4. USER SEGMENTS
|
| How effective is Coldry Blasting in the Food Industry? |
| As the cleaning process does not involve the use of water or chemicals, Coldry blasting is an ideal solution. Removing baked-on food deposits from ovens, cleaning mixers and moulds, removing paper and adhesives from packaging machinery are some of the benefits we can achieve using Coldry blasting. Irrespective of surface - plastic or metal, hot or cold, the effectiveness remains the same.
|
| What about Coldry Blasting on Electronics ?
|
| Using Coldry blasting, we can clean dirt and soot from electronics without making them wet or using chemicals. Coldry blasting can be used on units of up to 29 kW without disconnecting the power supply. By cleaning the electronic components at regular intervals, unexpected power failure and resulting production shutdown can be avoided.
|
| Is Coldry Blasting effective on Packaging Machinery ?
|
| On the packaging machinery, adhesive residues and other dirts are completely removed using Coldry blasting. This reduces the unexpected shutdown as package line flow is improved considerably. Replacement of adhesive nozzles and chain drives would be reduced due to Coldry blasting, resulting in large savings.
|
| Can Coldry Blasting be used in Printing?
|
| In printing segment, Coldry blasting removes wet and dry ink, powder, paper dust and adhesive residues. This results in minimal number of unexpected shutdowns, improvement of product quality and reduction of maintenance time.
|
| Can Coldry Blasting be used on Moulds?
|
| Yes. You can clean moulds using Coldry blasting during production and this reduces downtime. Since it is a gentle process, the mould surfaces are not damaged.
|
| Can Coldry Blasting be used on Buildings?
|
| Yes. By removing soot and dirt from buildings, Coldry blasting can restore surfaces. As against cleaning using traditional cleaning agents involving the use of chemicals, Coldry blasting cleaning does not warrant removal of any machinery or furnishings. In addition, both external as well as internal cleaning are equally effective through this method.
|
| What about in the Pharmaceutical Industry?
|
Coldry blasting is a clean and dry process that effectively and quickly removes coatings and deposits from moulds, conveyors, containers, mixers and other production equipment. The conventional steam and water-based cleaning methods can produce health risks as steam can provide a breeding ground for bacteria and other micro-organisms. Coldry blasting is a dry process which eliminates such problem.
In addition, cleaning with water and steam can increase the risk of accidents with electronics. However, when Coldry is used it vaporises on contact with the surface being cleaned, leaving no no secondary waste material. Hence Coldry blasting is 100% safe.
