The RBS block units are robust, weatherproof air handling systems designed for efficient air supply and exhaust. They are equipped with advanced features for durability and performance, suitable for various industrial applications.
Specifications
The document outlines various technical specifications for air handling and fire-extinguishing systems. Key specifications include:
  • Fan section with an air-handling capacity of 2800 m3/h, external pressure of 300 Pa, total pressure of 491 Pa, power consumption of 0.53 kW, operating speed of 2204 r.p.m, sound power level of 79 dB (A), and efficiency of 73%.
  • Materials used include polyamide 6.6 and seawater-resistant aluminum for the impellor.
Procedures
The document describes the installation and operation procedures for the RSC systems and REVEN®-O-MAT fire-extinguishing systems. It emphasizes the importance of proper sensor placement and the integration of components for efficient operation.
Standards and Norms
The REVEN®-O-MAT system is approved by Underwriters Laboratories® (UL) and the National Fire Protection Association (NFPA), adhering to standards such as UL Standard 1254, UL Standard 300, NFPA 96, and NFPA 17A.
Recommendations
Recommendations include ensuring that the RSC system is designed with the correct number of sensors based on kitchen equipment rather than hood length. The document also advises that fire-extinguishing systems should be designed by trained technical personnel to ensure proper protection and compliance with standards.
Key Components
The RSC system includes sensors, a power supply unit, and a control signal system. The REVEN®-O-MAT system comprises extinguishing agent tanks, nozzles, and a mechanical trigger unit. The document details the materials and design of piping and nozzles, emphasizing the importance of using stainless steel for durability.
Critical Information
For the RSC system, the control signal ranges from 0 to 10 V, suitable for controlling external devices like fans and servomotors. The REVEN®-O-MAT system uses ANSULEX-LpH as the extinguishing agent, which reacts with burning grease to prevent re-ignition.
Overview
The document provides technical specifications and installation guidelines for various fire-extinguishing systems and air cleaning systems, specifically designed for kitchen environments and other spaces.
Fire-Extinguishing Systems
  • Types of Detectors: There are two types of detectors: end detectors and series detectors. End detectors are located at the end of the trigger rope, while series detectors are installed between the trigger mechanism and the end detector. Up to 15 detectors can be installed in one line.
  • Extinguishing Agent Tank: The tank has a capacity of 11.4 liters, made of stainless steel, with an operating pressure of 6.89 bar, test pressure of 20.86 bar, and bursting pressure of 41.37 bar.
  • REVEN®-O-MAT System: This system requires customer-provided cabling and recommends an alarm horn for acoustic alerts. The system is triggered mechanically and requires a shut-off system for power supply to kitchen equipment.
  • Guardian System: Designed for private kitchens, it integrates into cooker extraction hoods and is approved by UL and German testing institutes. It features a pressure tank, spray nozzles, and a power-supply shut-off unit.
Ultra Cleaner System
  • Type UC-OH2: This air cleaner is suitable for commercial kitchens, hotels, and private homes. It effectively removes cigarette smoke, fine dust, and allergens, ensuring clean air.
  • Technical Specifications: Dimensions are 650 mm in height, 400 mm in width, and 450 mm in depth, with a weight of 30 kg. It operates at 110 V 60 Hz or 220 V 50 Hz, with an air-handling capacity adjustable up to 500 m³/h and a noise level between 0 dB(A) to 50 dB(A).
  • Air Cleaning Efficiency: The system achieves over 99.97% efficiency for particles larger than 0.3 µm, using a washable pre-filter, optional gas filter, and a HEPA® H13 filter.
Recommendations and Best Practices
  • Ensure proper installation of soldered struts behind grease filters in extraction hoods.
  • Install a shut-off system for power supply to kitchen equipment to guarantee system effectiveness.
  • Consider installing an alarm horn for immediate alerts during system activation.
