CHEMPENN

CHEMPENN is a brand of hydrocarbon refrigerants supplied in small, single-use cylinders. The product line available through 3G Electric includes R-290 (propane) and R-600A (isobutane), both classified as A3 refrigerants under ASHRAE safety group designations. These are not blends; they are single-component hydrocarbons with low global warming potential (GWP) and zero ozone depletion potential (ODP). The cylinders are white, with capacities ranging from 10.6 oz to 14.4 oz, and each carries a manufacturer part number for traceability. Applications listed for the supplied SKUs include domestic refrigerators and dehumidifiers, where the refrigerant is used as the factory charge or for service recharge. R-290 and R-600A are common in small hermetic systems because they offer favorable thermodynamic properties and are compatible with conventional mineral oils in many cases. However, A3 classification means they are flammable, so handling requires adherence to local safety codes, proper ventilation, and leak detection. 3G Electric stocks multiple SKUs of CHEMPENN refrigerants, covering different cylinder sizes and application labels. The product data includes MPNs, cylinder weights, and intended use, allowing procurement and maintenance teams to match the correct refrigerant to the equipment. Because these are hydrocarbon refrigerants, they are subject to transport and storage regulations; 3G Electric provides logistics support for global shipments, including documentation as required. The brand does not publish extensive technical literature in the public domain, so specifiers should rely on the cylinder labeling, safety data sheets, and the equipment manufacturer's requirements. For plant engineers and maintenance managers, CHEMPENN refrigerants offer a direct replacement for high-GWP refrigerants in specific small-charge systems, provided the system is designed or retrofitted for flammable refrigerants. The 10.6 oz and 13.1 oz R-290 cylinders and the 10.6 oz and 14.4 oz R-600A cylinders are suitable for service work where small charges are needed. 3G Electric supplies these products without regional restrictions, shipping from Singapore to global destinations. The catalog includes part numbers 111032, 111034, 111035, and 111039, each corresponding to a specific refrigerant, cylinder size, and application. This allows buyers to select the exact SKU for their inventory. No performance ratings, certifications, or approvals are claimed here beyond what is stated on the product labels and safety data sheets. For technical selection, always consult the equipment manufacturer's specifications and local regulations regarding flammable refrigerants.

Frequently asked questions

Common questions about CHEMPENN from 3G Electric.

What is the difference between CHEMPENN R-290 and R-600A refrigerants?

CHEMPENN R-290 is propane, while R-600A is isobutane. Both are hydrocarbon refrigerants with A3 flammability classification. R-290 has a boiling point of approximately -42°C at atmospheric pressure, making it suitable for medium-temperature applications. R-600A boils at about -12°C, which is better for low-temperature applications like domestic refrigerators. The CHEMPENN line supplies both in small white cylinders: R-290 in 10.6 oz and 13.1 oz sizes, and R-600A in 10.6 oz and 14.4 oz sizes. Selection depends on the system design and the equipment manufacturer's specification.

What are the cylinder sizes available for CHEMPENN R-290?

CHEMPENN R-290 is available in two cylinder sizes through 3G Electric: a 10.6 oz white cylinder (MPN 111035) and a 13.1 oz white cylinder (MPN 111034). The 10.6 oz cylinder is labeled for refrigerator applications, while the 13.1 oz cylinder is labeled for dehumidifiers. Both are single-use cylinders and contain A3 flammable refrigerant. Always check the part number and label to ensure the correct size and application for your service needs.

Is CHEMPENN R-600A suitable for use in dehumidifiers?

The CHEMPENN R-600A SKUs listed in the 3G Electric catalog are labeled for refrigerator applications, not dehumidifiers. The R-290 SKU 900H03 is specifically labeled for dehumidifiers. If you need a refrigerant for a dehumidifier, verify the equipment manufacturer's recommendation. R-600A can be used in some dehumidifiers, but the CHEMPENN products supplied here are designated for refrigerators. Always follow the equipment nameplate and local regulations for flammable refrigerants.

What safety classification applies to CHEMPENN hydrocarbon refrigerants?

CHEMPENN R-290 and R-600A are classified as A3 refrigerants under ASHRAE Standard 34. A3 indicates lower flammability limit and higher heat of combustion, meaning they are flammable. This classification requires specific handling, storage, and transport precautions. Systems using these refrigerants must be designed for flammable refrigerants, with proper ventilation and leak detection. Service technicians should be trained on flammable refrigerant handling. 3G Electric provides safety data sheets and shipping documentation as required for global transport.

Can CHEMPENN R-290 be used as a drop-in replacement for R-22 or R-134a?

CHEMPENN R-290 is not a drop-in replacement for R-22 or R-134a. It is a hydrocarbon refrigerant with different pressure-temperature characteristics, and it is flammable (A3). Retrofitting a system from non-flammable refrigerants to R-290 requires changing components, updating safety measures, and ensuring the system is rated for flammable refrigerants. The equipment manufacturer must approve the use of R-290. The CHEMPENN SKUs supplied by 3G Electric are intended for systems designed for R-290, such as certain domestic refrigerators and dehumidifiers.

What documentation is provided with CHEMPENN refrigerant cylinders from 3G Electric?

3G Electric supplies CHEMPENN refrigerant cylinders with the manufacturer's part number and cylinder labeling. Safety data sheets (SDS) are available upon request. For global shipments, 3G Electric provides logistics support including transport documentation as required for A3 flammable refrigerants. The cylinders are not returnable or refillable; they are single-use. Always refer to the SDS and local regulations for safe handling, storage, and disposal.
