CDI FIRE Product Line
CDI FIRE is a product line of the SMH SISTEMAS Group composed of cylinders for fire protection systems that use chemical and inert agents for fire suppression.
CDI FIRE line was developed in Brazil in compliance with national legislation and ABNT standards (Brazilian Association of Technical Standards), Technical Instructions of the Fire Department and international standard: NFPA 2001 (National Fire Protection Association).
CDI FIRE’s cylinders for fixed fire suppression systems use very high quality components and inputs, they are imported or national materials certified by entities that recognize the high standard of quality.
CDI FIRE’s products are used to fire protection in mission critical environments and special risks throughout Brazil and provide maximum protection with an excellent quality and cost-benefit ratio. CDI FIRE is a reference in service agility in record time, due its local stock for the prompt service of the Brazilian market.
CDI FIRE Solutions
Cylinders for Fixed Fire Suppression Systems with Low Pressure Clean Agents:
Cylinders Charged with clean agents (gases): HFC-125, HFC-227ea and FK-5-1-12 Fluid @ 24 bar (360 psi)
The cylinders have electromechanical valves with 24 Vdc solenoid, manometers with automatic supervision, manual and pneumatic actuators, high pressure hoses and other accessories for perfect installation.
Available sizes: 32L, 52L,100L, 240L and 375L
All cylinders loaded with clean agents are supplied with hydraulic calculation built in NFPA 2001 standard software and isometric for installation.
Cylinder Assembly Features:
The cylinders are made of welded carbon steel, painted in red, DOT / ASME Section VIII Division 1 (Compress 2017 Build 7700) standard , for working pressure up to 40 bar, filled with the clean agent defined in the project (HFC-125, HFC-227ea or FK-5-1-12 fluid).
The cylinder is sealed by an electromechanical valve with a 24 Vdc solenoid that is kept closed by the pressure of the clean agent and has a safety device that breaks when there is an increase in internal pressure when reaching the safety limits predetermined in international standards.
