Product Highlight: Hi-Flow™ Control Valves

Hi-Flow™ Control Valve

Hi-Flow™ control valves are single seated, top or cage guided globe valves – probably the simplest, from a construction standpoint, yet most versatile control valve in use. The Hi-Flow™ valve can fit applications with a smaller size valve since the valve has a greater flow capacity than most conventional valves of the same size. Coupled with a high flow capacity, the Hi-Flow™ valve maintains a wide rangeability of 50:1 to ensure precise control.

Energy Savings from On-Demand Ventilation

Most local regulations for indoor air quality are designed around ASHRAE Standard 62. This standard specifies the minimum amount of outdoor air flow into an occupied space to be between 15 to 60 CFM per person, but more commonly building regulations require 15 to 20 CFM per person. Besides actually measuring the air flow, ASHRAE also defines indoor air quality using the concentration of carbon dioxide gas in the air. Carbon dioxide is recommended to be less than 1000 PPM. When sizing the air handling unit for a building, engineers will make the design exceed the maximum occupancy in the building or space to ensure that they will always be able to meet the minimum air requirements. In most cases, buildings or mix used spaces rarely are occupied at these maximum levels, thus the amount of conditioned air supplied is usually much greater than what is required. As building owners aim to reduce energy costs and operate buildings more efficiently, wasted energy of conditioning unneeded outside air has been a good place to start.

Protecting Newborn Puppies with Dwyer Temperature Controllers

Doberman Mother with Litter of Puppies in a Whelping Box

A whelping box is designed to protect puppies during birth, also called whelping, by keeping them safely contained, protected from the cold, and from being accidentally crushed or smothered by their mother.

Whelping boxes vary in construction, from cardboard boxes which have been found and re-purposed, to enclosures which have been designed specifically for the protection and care of the newborns. Continue reading “Protecting Newborn Puppies with Dwyer Temperature Controllers”
