Dual Tank Enclosure 429872

The Ansul 429872 is a protective enclosure designed to house two ANSUL agent cylinders in commercial kitchen environments, providing secure mounting and shielding for dual-cylinder ANSUL R-102 system configurations. The dual tank enclosure protects the agent cylinders from physical damage, grease contamination, and accidental impact in the busy commercial kitchen environment — where the cylinders are typically installed in the hood area or behind cooking equipment and are subject to the same harsh conditions as all kitchen suppression components.

In larger commercial kitchen fire suppression system configurations, two agent cylinders may be required to provide sufficient wet chemical agent volume for complete coverage of all protected cooking appliances. The 429872 enclosure provides a single, organized mounting solution for both cylinders — keeping them positioned correctly per the ANSUL R-102 system design, protecting the actuation tubing connections from physical stress, and presenting a professional, code-compliant installation appearance. The ansul box and ansul cabinet product family provides various enclosure configurations for different R-102 system cylinder counts and installation environments.

Built to meet UL and NFPA standards for commercial kitchen fire suppression system component housing, the 429872 is part of the ANSUL fire protection system components catalog available through authorized ansul distributors. Inspect the enclosure at every semi-annual NFPA 17A and NFPA 96 inspection for physical damage, corrosion, and proper mounting security. The enclosure cover must remain closed and latched during system standby to maintain the protection it provides to the cylinder assemblies and actuation hardware.

Mounting and Positioning

Install the 429872 enclosure per the ANSUL R-102 system design drawings, positioning the dual cylinders in the correct location relative to the Automan control head and distribution piping per the ansul system for hood installation requirements. The enclosure must be securely anchored to structural substrate — verify the mounting fasteners and substrate can support the gross weight of both fully charged cylinders. Route actuation tubing through the enclosure per the ANSUL R-102 system manual without sharp bends or tension.

Semi-Annual Inspection

Inspect the 429872 enclosure and its contents at every semi-annual NFPA 17A and NFPA 96 inspection. Verify the enclosure is secure, the enclosure cover closes and latches correctly, both cylinder brackets are tight, and no physical damage or corrosion is present. Document enclosure condition in the fire suppression system inspection record.

Is the 429872 required or optional for dual-cylinder R-102 installations?

The ANSUL R-102 system design documentation specifies the required cylinder mounting configuration for each system design. In many commercial kitchen environments the dual tank enclosure is specified as the correct installation method — it provides both the required structural support and the protective enclosure for the cylinders. Verify whether the 429872 is specified for your system design using the ANSUL R-102 system documentation or by consulting authorized ansul distributors.

Can the enclosure be used for a single cylinder?

The 429872 is designed for dual cylinder configurations. For single-cylinder R-102 systems, the appropriate single-cylinder bracket or enclosure should be used. Using the dual enclosure for a single cylinder without proper securing of the unused cylinder position can create an unstable installation. Verify the correct enclosure or bracket for your specific R-102 system configuration through the ANSUL parts documentation.
