DALEMANS deals with all types of gas.
Products & services
DAX 420 Explosive Gas detector
The DAX 420 Explosive Gas detector is intended to monitor CH₄ / C₃H₈ / C₄H₁₀ / CO₂ / C₇H₈ / and C₅H₁₂ gases in industrial sectors and laboratories. It must be combined with a control panel to activate the connected servo-controls: solenoid valve cut-off, sirens, flashing lights, etc.
DAT 420 Toxic Gas and Oxygen detector
The DAT 420 ATEX Toxic Gas and Oxygen detector is intended for monitoring CO, O₂, NH₃, CL₂, NO₂ and SO₂ gases for the commercial and industrial sectors. It must be combined with a central unit to activate the connected controls: air extractors, solenoid valve cut-out, etc.
Technical studies
DALEMANS uses its expertise and experience to carry out technical studies and drawings for design offices and fitters, electricians or security system fitters. DALEMANS analyses the specifications in order to design the best adapted solution. DALEMANS carries out technical and normative studies for the integration of new gas detection systems. DALEMANS accompanies and advises customers on their choice of the most suitable equipment. DALEMANS takes care of complete project management, from installation to commissioning.
Maintenance
The goal of maintenance is to ensure that the equipment, control units, detectors and accessories of a gas detection installation remain operational in the long term. It also allows for the responsible and conservative management of the risks of asphyxiation, intoxication or even explosion. DALEMANS takes care of the maintenance of gas detection systems of different brands, whether for HVAC systems or for laboratories or industries.
D•420 Gas or Oxygen detector
The D•420 Gas or Oxygen detector is intended to monitor CO, CO₂, NO₂, NH₃ or O₂ gases for car parks, laboratories and refrigerated rooms. It must be combined with the U-V6/U-C2 control units in order to activate the associated servo-controls: sirens, flashes, solenoid valve cut-off, etc.
D•TEX 420 Explosive Gas Detector
The D•TEX 420 Explosive Gas detector is intended for monitoring the concentration of H₂, CH₄, C₃H₈, C₄H₁₀, LPG and CNG gases in car parks and laboratories. It must be combined with an alarm control panel to activate the associated servo-controls: ventilation, flashing lights, etc.
Co-Engineering
Creation of new gas detection solutions in collaboration with customers Thanks to our integrated R&D department, DALEMANS develops, in collaboration with its customers, new gas detection projects or new systems. DALEMANS has positioned itself as the partner of choice in the creation of customised systems thanks to its expertise and mastery of the entire gas detection value chain. DALEMANS develops customised R&D projects, both in terms of products and software.
Commissioning
Commissioning, inspection and calibration of new gas leak detection systems DALEMANS manages all that is necessary for the safety and testing of new systems for both the tertiary and industrial sectors. The after-sales service department and its teams of technicians handle the commissioning and calibration of any gas detection system.
New S.LINE range of gas detection units
An all-in-one solution In 2025, DALEMANS launches its new S.Line range. These centrals offer an all-in-one solution for parking (S.Vx) and (S.Vx) and laboratory (S.Lx) applications. Time-saving installation With their high I/O capacity and flexible wiring (CAN Bus and 4-20mA), these new control units save time on fixed gas detection installations, thanks to a single configuration and calibration procedure. FEATURES - 1 CAN bus interface (2 lines) - Max. number of sensors 240 (CAN bus), 16 4..20 mA detectors - Relay outputs: 6 + 1 fault (expandable to 18 + 1 fault) - Modbus TCP interface for easy networking - Integrated 7” touchscreen - IP65 PROTECTION EXPANSION OPTIONS: - 1x CAN bus expansion board (4 lines) OR up to 2x 4..20 mA expansion cards (8x analog inputs)
