Oxygen, Nitrogen, Argon, CO₂, Acetylene, Helium, Hydrogen and custom mixes — in cylinders, dewar tanks and bulk PLC tanks. Supplied to all of Peninsular Malaysia since 1998.
Callserv supplies industrial, medical and specialty gases — in compressed cylinders, liquid dewar tank, and PLC bulk tanks — to clients across Peninsular Malaysia. We serve manufacturers, oil & gas operators, welders, fabricators, hospitals, laboratories, and food & beverage producers with reliable, traceable, and DOSH-compliant gas supply.
Choose by gas type. Custom mixtures and high-purity grades available on request.
Industrial-grade oxygen for cutting, brazing, welding and metal fabrication; medical-grade oxygen for healthcare clients. Cylinders of various capacities and liquid oxygen for high-volume users.
Compressed and liquid nitrogen for inerting, purging, pressure testing, food packaging, electronics manufacturing, cryogenic freezing and offshore purging. Cylinders, Dewar tanks and PLC bulk tanks.
High-purity argon for TIG (GTAW) and MIG (GMAW) welding shielding, stainless steel and aluminium fabrication, and heat-treatment furnace blanketing. Available in cylinders and liquid form.
Welding-grade CO₂ for MIG/MAG welding, beverage-grade CO₂ for the food and beverage sector, and industrial CO₂ for pH control and inerting.
Premium-grade acetylene for oxy-fuel cutting, brazing and flame heating in workshops and on construction sites.
Helium for leak testing, balloon use, laboratory work and gas chromatography carrier applications.
Hydrogen for analytical instruments, reduction reactions and laboratory applications.
Custom-blend calibration gases, shielding gases and laboratory mixtures formulated to your specification.
Choose the format that matches your consumption profile and storage footprint.
Standard industrial cylinder sizes for low-to-medium volume users — welding shops, labs, clinics and field service.
6, 12 or 16-cylinder bundles for higher consumption. Custom rack dimensions fabricated in our workshop.
Insulated Dewar tanks in various capacities for liquid nitrogen, oxygen and argon.
High-volume bulk supply for production lines and cryogenic users.
Mobile refilling of your Dewar or PLC tanks at your facility — eliminating tank-rotation downtime.
Custom-designed manifold systems matched to your flow, regulator and safety requirements.
Our mobile decanting service refills your Dewar tanks and PLC tanks at your facility, eliminating the downtime caused by tank rotation. Common use cases include semiconductor lines, offshore platforms, livestock breeding centres (artificial insemination cryostorage) and laboratories.
Schedule On-Site RefillOur Indera Mahkota facility houses a licensed refilling plant and hydrostatic pressure testing station — keeping your cylinders certified, traceable, and safe.
Customer-owned cylinders refilled to specified purity and pressure, with batch traceability.
DOSH-compliant hydrostatic testing of compressed gas cylinders to verify mechanical integrity before re-entry to service.
Visual inspection, valve check, cleaning and recertification — keeping your fleet compliant.
Inert gas purging service for vessels, tanks and pipelines docked at Kuantan Port and East Coast facilities. Eliminates hydrocarbon vapour and oxygen prior to maintenance hot-work — protecting personnel and assets.
On-request inspection of propane piping and storage to detect leaks across the entire system. Performed for industrial kitchens, LPG-fuelled production lines and commercial installations.
