We all are facing an unprecedented challenge. The medical and healthcare communities in the United States and across the world are responding to a medical emergency involving spread of the Novel Coronavirus Disease (“COVID-”). On January , , the World Health Organization (“WHO”) declared the outbreak of COVID- a Public Health Emergency of International Concern (“PHEIC”), and, on March , , the WHO Director General declared COVID- a pandemic. On March , , President Donald J. Trump declared a National Emergency in the United States due to the COVID- outbreak.

All Sepehr Electric vented gas heaters are equipped to three different safety systems: ) environment oxygen control system (Oxypilot ODS), this fully stops the gas flow upon oxygen lowering in the room to less than normal limit. ) Thermocouple, the thermocouple automatically shuts off the gas flow if the flame of the heater is turned off accidentally. ) Pressure governor, the governor will permanently regulate the input gas pressure in order to control and stabilize the output pressure in a safe and certain range.

Sepehr Electric high pressure side draft evaporative coolers (also referred as side flow). The air cycle operation of this device is to pulling the air from outside the cooler. Once the air is cooled inside the cooler, it is sent sideward by the blower, creating an side draft of air. This air flows into ducts that spreads the cool air through the house. The perfect place to install this unit is on the roof but could certainly be installed and perfectly used also on trusses or balconies.

Cellulose water coolers share almost similar air cooling qualities like the Aspen pad coolers. What makes them different from each other is the kind of evaporation interface. In cellulose water cooling systems, compact cellulose pads are used instead of aspen pads. Cellulose pads are made of cellulose paper sheets which are very thin, with high capillary and absorption capability. These pads are regular and wavy in form, have some certain grooves, special groove angels and function with water up to temperature of º. It is recommended to maintain the pH level of the water between and .
