Since 1996, we have specialised in supplying explosionproof electrical equipment to industrial clients in Singapore and throughout Southeast Asia. With nearly three decades of experience in hazardous-area solutions, we understand the critical importance of products that maintain operational safety and integrity in environments where explosive gases, vapours and combustible dusts are present. To uphold these high standards, we have selected Killark as our principal brand partner, a globally recognised manufacturer with a long history of engineering rugged, high-performance explosionproof control products trusted in demanding applications worldwide.
Dedicated Control Station Solutions – Killark HKH Series
This website focuses on the Killark HKH Series Control Stations, explosion protected control devices designed for classified industrial environments. The HKH series offers high flexibility and customisation, providing tailored operator interfaces integrating push buttons, pilot lights, selector switches, emergency stops, and other control functions. These control stations can accommodate up to six user-specified devices in a single enclosure, allowing mix-and-match configurations to suit operational requirements.
Certifications and Hazardous Area Approvals
Killark HKH Series control stations are engineered and certified for use in hazardous locations under multiple global safety standards:
-
ATEX – Approved for Zone 1 and Zone 21 hazardous areas (gas and dust) in the European Union.
-
IECEx – International certification for explosion-protected equipment providing consistent global compliance.
-
UL / cULus – Certified for North American hazardous classifications including Class I Division 2 and associated Group ratings.
-
Ingress Protection – IP66 rating ensuring dust tightness and robust water resistance.
These certifications confirm that the HKH series is suitable for environments such as offshore platforms, petrochemical plants, refineries, mining facilities, and other industrial sites where strict regulatory compliance and safety are mandatory.
Product Features and Benefits
Explosionproof Design for Classified Workspaces
The HKH control stations are engineered to contain internal arcs and prevent ignition of flammable materials in the surrounding atmosphere. They meet rigorous explosionproof requirements for both gas (Group IIC) and dust (Group IIIC) hazard groups. This protective design supports continuous safe operation in classified areas (e.g., Zones 1 & 21), reducing risk and supporting compliance with local safety regulations.
Customisable Control Interfaces
One of the defining benefits of the HKH series is its modular scalability. Customers can select combinations of:
-
Push buttons (momentary or maintained)
-
Emergency stop buttons
-
Selector switches (with or without lockout covers)
-
Pilot lights (LED)
These operator devices support effective local control and indication functions for motors, lighting, pumps and other industrial loads.
Wide Operating Conditions
Killark HKH control stations are rated for operation in extreme temperature environments, typically -50°C to +60°C, enabling use in both tropical and temperate industrial installations without derating.
Robust Mechanical Construction
Killark HKH enclosures are available in different materials, providing durability suited to the installation context:
-
316 Stainless Steel – Offers excellent corrosion resistance and mechanical strength, ideal for marine, offshore, chemical and other corrosive environments.
-
Glass Reinforced Polymer (GRP) / Non-Metallic Options – Available in specific HKH non-metallic variants, these materials deliver high impact resistance, antistatic surface properties and ultraviolet protection, making them suitable where metal enclosures may be disadvantageous.
Both enclosure styles maintain explosionproof performance while offering compatibility with a range of conduit entries, sealing methods, and accessory options (such as lockout/tagout attachments).
Enhanced Safety and Operational Efficiency
-
Fail-safe control of critical functions (e.g. START/STOP, ON/OFF).
-
Clear indication via LED pilot lights across AC/DC ranges.
-
Ease of installation and maintenance through standardised mounting features and DIN rail or cover mounting options for internal components.
Typical Applications
Killark HKH Series control stations are widely deployed in industrial segments where hazardous area protection is essential, including:
-
Oil & gas processing facilities
-
Chemical and petrochemical plants
-
Power generation stations
-
Marine and offshore installations
These industries demand control equipment that not only meets stringent safety standards but also delivers dependable performance under continuous operation.
