History

• 1975: Thomas M. Trachsel establishes ASCO CARBON DIOXIDE LTD in Switzerland for sale and marketing of a wide range of CO₂ equipment.

• 1987: ASCO acquires Carbonic Industries Ltd which later becomes ASCO New Zealand.

• 2005: ASCO acquires Diffusion Hydraulique S.A.R.L. which becomes ASCO France.

• 2007: ASCO becomes part of the Messer Group.

• 2011: ASCO acquires Remco in Switzerland – Production site of dry ice production and dry ice blasting machines.

• 2014: ASCO and BUSE Gastek pool their strengths with a merger in CO₂ process and dry ice technology. Therefore ASCO even increased its vast practical experience in the wide field of CO₂ and dry ice to over 130 years.

• 2016: Foundation of North American subsidiary ASCO CARBON DIOXIDE INC

• 2020: Digitalization of ASCO pelletizers to provide production and machine data on a new customer platform. Remote support and remote monitoring are now standard features.

 

PRODUCTS

ASCO CO₂ Pressure Reducing Valve

The ideal and reliable high-flow CO₂ pressure reducing valve for use with CO₂ gas or liquide.

 

ASCO CO2 Flowmeter

The ASCO CO₂ Flowmeter has been developed to accurately measure CO₂ gas flow in closed pipes.

The power unit, which supplies 230 V, operates a microprocessor controlled flow computer and one sensor.

The ASCO CO₂ Flowmeter is a complete system which is supplied fully calibrated and wired and therefore very easy to install.

ASCO CO2 Gas Detector

ASCO CO₂ Gas Detectors are used to protect personnel wherever CO₂ gas or dry ice is used in closed areas, for example during dry ice blasting or when producing dry ice.

ASCO offers wall-mounted solutions for area monitoring and portable devices for personal protection. ASCO CO₂ Gas Detectors ensure continuous and automatic CO₂ content measuring in the ambient air using infrared absorption measuring (NDIR). This technology is very troubleresistant to temperature variations or air draughts and therefore measures very accurately. The CO₂ gas detectors are very simple to handle and all components are built splash proof.

 

PH-Neutralisation with CO2

Typically, the ASCO CO₂ Gas Dosing System is used together with water desalination plants. The system is equipped with a CO₂ pressure reducing valve, filtration unit, CO₂ gas flowmeter, CO₂ regulating valve, pressure gauges, safety valves and a completely pre-wired control cabinet. In case of maintenance the system provides a manual by-pass line, which also can be monitored by the flowmeter. Herefore, changing a filter cartridge or doing any other service work on the system is quick and easy!

As raw and fitting material ASCO uses mainly stainless steel. This makes the system very resistant and extends the products life cycle.
 

ASCO Atmospheric CO2 Vaporiser

The ASCO Atmospheric CO₂ Vaporiser is the most economical solution for vaporising liquid CO₂.

We offer Atmospheric CO₂ Vaporisers in various capacities with either stainless steel or copper tubings.

The atmospheric ASCO CO₂ Vaporiser has been developed to drastically reduce CO₂ vaporisation costs. Ambient air, which is available at no cost, is used to achieve energy savings of over 95% compared to standard electric vaporisers. The fans are automatically controlled temperature dependent and only work if a consumer equipment is in operation. As each vaporiser is supplied prepiped and prewired, installation can be made within minutes. Bases for floor mounting are included. In addition to our standard models, we offer individual solutions of modern and easy to maintain CO₂ vaporisers. In accordance with your requirements, we provide you with a suitable CO₂ vaporiser.

Available capacities:
200 kg/h, 300 kg/h, 500 kg/h und 1‘000 kg/h (440 lb/h, 661 lb/h, 1102 lb/h, 2205 lb/h)

Advantages

 

ASCO CO2 Cylinder Filling System LH900

The LH900 Liquid CO₂ Filling System has been developed as a universal unit for the filling by weight of high pressure CO₂ cylinders.

This system with automatic revert and automatic shut-off comprises pump with motor on base frame, pulleys, drive belt, one safety valve 130 bar, pressure gauges for tank- and filling pressure, solenoid valve, motor switch and electric control box.

The ASCO LH900 Liquid CO₂ Filling Pump has been developed as an universal unit for filling high pressure CO₂ cylinders by weight. Like all ASCO Equipment, the Cylinder Filling and Weighing System is thoroughly factory pretested before despatch. Thanks to the separate control unit, the pump can be placed in a different location.

Easy operation Switch on your ASCO LH900 and the unit automatically tares itself to „0“ which will show on the indicator display. After placing a cylinder on the platform, the display will show the accurate tare weight of the cylinder, allowing the operator to check whether the empty cylinder weight is correct. The chosen filling weight can now be set on the display by pressing the relevant keys (when filling the same size of cylinder, the filling weight needs only be entered once). When the desired filling weight is reached and displayed, the solenoid valves of the ASCO LH900 will automatically switch to run the system in by-pass. The CO₂ cylinder can now easily be disconnected.

 

ASCO CO₂ Transfer Pump

ASCO offers a variety of different low to low CO₂ Transfer Pumps. The pumps have hardened steel gears and thrust washers to give long service life.

ASCO CO₂ Transfer Pumps have steel housings and long life shaft seals. The pumps have hardened steel gears and thrust washers to give long service life. The mechanical seal fitted provides leak free operation.

These economical pumps need no lubrication and no day-to-day maintenance. A unique design allows parts to adjust automatically for wear. Highest efficiency is maintained for a very long time. Installation is simple as no chain or belt drives or gear reduction motors are required. Pumps can be directly connected to standard speed low-cost electric motors. By simply changing the shaft rotation, pumps can be used to pump in or out through the same piping.

 

ASCO CO₂ Gas Purity Tester

The ASCO CO₂ Gas Purity Tester has been designed to measure the purity of CO₂ up to 99.995 % in a quick, easy and reliable way. Essential for bottling plants, breweries, beverage manufacturers and industrial gas companies.

The complete kit contains all equipment for a simple, safe and fast CO₂ gas purity test and is complete with easy instructions (step by step pictures on a laminated A3 sheet). The ASCO CO₂ Gas Purity Tester (stainless steel) can be used either wall-mounted or free standing.

 

ASCO CO₂ Carbonation Tester

The ASCO CO₂ Carbonation Tester is used to identify any strange odour and/or taste in CO₂. With this simple, easy to use kit you can check the quality of your liquid or gaseous CO₂ from bulk tanks or CO₂ cylinders.

The set includes a CO₂ carbonation unit, CO₂ cartridge with special inner coating, adaptors made of stainless steel and emptying device for CO₂ cartridge and easy instructions.

Following the easy, laminated an coloured step-by-step instructions with pictures, a sample of water carbonated is tested. The carbonated water is compared for taste and smell with a non-carbonated sample of the same water.

 

ASCO CO₂ Dew Point Tester

The ASCO CO₂ Dew Point Tester reliably indicates the dew point (moisture content) of your CO₂.

This equipment makes it easy to measure the dew point of liquid and gaseous CO₂. A laminated, illustrated step-by-step short instruction sheet in A3 format and a detailed instruction manual are supplied with each tester.
The ASCO CO₂ Dew Point Tester (stainless steel) can be used either wall-mounted or free-standing.
