Preventive maintenance of MEP Equipment

  What is a Humidifier? * A humidifier is a device that adds moisture to the air to maintain a comfortable humidity level in a building or space. *Specification of Humidifier: * 🔹 *Capacity*: Measured in gallons per day (GPD) or liters per hour (LPH). 🔹 *Humidification Range*: The range of humidity levels the device can maintain. 🔹 *Control System*: May include humidistats, sensors, and controllers. *Elements of a Humidifier: * 🔹 *Water Supply*: Provides water to the humidifier. 🔹 *Humidification Element*: May include evaporative pads, steam generators, or ultrasonic transducers. 🔹 *Distribution System*: Delivers humidified air to the space. *Role of Humidifier in HVAC System: * ✨ *Maintaining Humidity Levels*: Humidifiers add moisture to the air to maintain a comfortable humidity level. ✨ *Improving Indoor Air Quality*: By maintaining optimal humidity levels, humidifiers can help prevent dry skin, respiratory issues, and damage to furniture and equipment. *Schematic Diagram:...

  FM-200 Fire Suppression System – Why Every Critical Facility Needs It Modern data centers, control rooms and telecom hubs can’t afford water-based fire suppression. This is where FM-200 (HFC-227ea) systems shine – a clean, fast-acting gaseous agent that protects people, equipment and operations. 🔹 Why FM-200 is Necessary Extinguishes fire in seconds without damaging electronics or leaving residue Safe for occupied spaces (non-conductive, non-corrosive) Minimizes downtime and business interruption 🔹 Key Components FM-200 agent cylinders with discharge valves Piping network and discharge nozzles Control & releasing panel (often integrated with the fire alarm panel) Pressure / flow switches and actuation devices Manual release & abort stations 🔹 How It Works 1. Smoke/heat detectors sense a fire and send a signal to the Fire Alarm / Releasing Panel. 2. The panel activates audible/visual pre-discharge alarms and delay timers. 3. FM-200 cylinders discharge the agent through ...

  Fire Pump Rooms that pass first time — design once, test cleanly 🎯 Purpose Provide code‑reliable water flow and pressure to sprinklers and standpipes during fire. Operate under loss of power and single faults, without operator intervention. (NFPA 20, NFPA 13, NFPA 14) 🧩 Anatomy / Components • Fire pump (diesel or electric) with listed controller. • Suction from tank with anti‑vortex plate and air‑release at high point. (NFPA 22) • Eccentric reducer flat‑on‑top and long, straight approach to the eye. • Discharge check + OS&Y gate, relief to safe drain/test header. • Jockey pump + pressure switch to maintain setpoint. • Test header/flowmeter line, gauges on suction/discharge, trench to drain. • Signals to FACP: pump run, controller trouble, phase loss, low fuel. 📐 Setpoints & Specs • Suction velocity ≤ 1.8 m/s; straight length ≥ 5–10 × suction Ø. • Anti‑vortex plate diameter ≈ 2 × outlet; elevation ≥ 0.5 × outlet above floor. • Normal pressure band: jockey ± ...
