HOLDRITE TESTRITE DWV Inline Testing Systems

holdrite testrite dwv

HOLDRITE TESTRITE DWV Inline Testing Systems

The DMV pipes in a home or business carry toxic gases, such as methane, safely away into the sewer system for chemical processing. Therefore, an airtight, leak-free DMV system is critical to everyone’s health and safety. However, some DWV testing techniques can be risky. For example, the traditional “ball method” of testing runs a risk of pipe leakage and/or spillage which can lead to contamination and/or injury due to falls. This simply isn’t the case with the Holdrite Testrite DWV Inline Testing System due to innovative engineering and a safety-first design.

Why Choose the Holdrite Testrite DWV Inline Testing System?

First, the innovative Holdrite Testrite system offers a safer alternative to other DWV testing systems. The Testrite does not require the use of an inflatable device, such as a bladder, which can cause water slippage during deflation. Instead, Testrite’s sealed system utilizes test wedges with triple protection o-rings to assure a watertight seal without leakage or contamination. Second, the Holdrite Testrite DWV inline testing system is easy to install with only a few tools and performs up to 5X faster than inflatable DWV testing devices. In addition, the Testrite is available for use with PVC, ABS, or cast iron piping systems and is appropriate for any building type.

Aquatherm Black System

aquatherm black system

Aquatherm Black System For Radiant Heating & Cooling

Hydronic radiant heating and cooling systems control the climate of a structure by circulating warm or cool water through tubing underneath or within a room’s floor. These systems work in two ways. To heat, the system radiates heat up from the floor to warm the room and objects touching the floor. To cool, the pipes of the system absorb heat from the room and distribute it back into the floor to provide cooling benefits. The Aquatherm Black System offers a radiant heat and cooling solution that is ideal for use in offices, hospitals, hotels, apartments, and other commercial applications. In addition to providing comfort as a quiet, efficient radiant cooling and heating solution, the Aquatherm Black System saves times, energy, money over traditional forced air systems.

Why Choose the Aqautherm Black System?

aquatherm black system

The Aquatherm Black systems utilize a series of wall or ceiling panels to heat or cool a space using radiant energy. With this technology, the temperature of a room is easily controllable. An automatic change-over between hot or cold water allows occupants to control a room’s temperature to create a suitable environment. Additionally, chambers in the systems allow for different temperatures in different zones of a building to keep all occupants at their desired temperature. For contractors, the Aquatherm Black System is easy to install. The complete system is 24.45 mm thick which allows it to fit below the plaster layer or behind drywall. In addition, the system’s pipe grids are made from rectangular manifolds which allow them to easily be linked for an easy connection. The Aquatherm Black System is available on a limited application, as-approved basis in the United States.

The SR Series of Maxitrol 2 Stage Regulators

 The SR Series of Maxitrol 2 Stage Regulators

Most two-stage regulator systems are made of two single stage regulators that operate in unison to reduce the pressure gradually in two stages rather than one. During the first stage, the pressure of the gas reduces to a preset level and is then passes on to the second stage. During the second stage, the regulator adjusts the pressure so the flame ignites and remains at the desired level. However, it’s no longer necessary to install two separate regulators on a unit if you use Maxitrol 2 Stage Regulators. That’s the Maxitrol SR series’ dual manifold system combines both gas pressure regulating and flame staging in a single unit. Some common applications for the Maxitrol’s 2 Stage Regulators include direct-fired heaters, hi-lo control (for outdoor heaters), LP natural gas switchover and industrial processing.

Maxitrol 2 Stage Regulators Specs

Maxitrol 2 Stage Regulators are made from solid aluminum and are available in 3/8″ thru 1″ threaded connections. All of SR series regulators are compatible with both NPT or ISO7-1 threads.  The SR series is suitable for natural gas, manufactured gas, mixed gasses, liquefied petroleum gases, and LP gas-air mixtures. All models may be powered by a 24 volt AC transformer. When the unit’s coil is energized, the appliance is a lowe fire. When the coil is de-energized, it is high fire. Continous regulation is maintained to hold the electricity set outlet at constant pressure. For specific information on individual models of the SR Series Maxitrol 2 Stage Regulators model click here.

Protection from Diseases in Water Systems

cooling towers, diseases in water systems
Click for Healthcare Facilities Today’s full article.

Healthcare Facilities Today posted a great article recently about protecting cities from diseases that proliferate in water systems. These bacteria can sometimes be deadly, so this type of protection cannot be understated.

The article mentions Delta’s Anti-Microbial towers, 6000 tons, installed at Lincoln Hospital in NY:

“These towers, which are rounded, not only solved the circulation problem but also have anti-microbial chemicals embedded into the tower’s HDPE material, which helps to prevent the growth of dangerous bacteria such as Legionella,” he says.

The towers the hospital selected were made by Delta Cooling Towers, which introduced the HDPE (high-density polyethylene) cooling tower in the 1970s.

While some cooling tower manufacturers now market a tower with an anti-microbial fill (the medium over which the hot water is distributed as it is being cooled), a vastly better option is to have a cooling tower featuring the fill, structural casing, and sump all composed of anti-microbial material.

The article is very informative and stresses the importance of these anti-microbial towers. I highly recommend you give the full article a read:


NH Yates offers many solutions to protect you from diseases in water systems, including the Delta towers mentioned in the article. See our linecards for more information, or get in touch with us today!

Flex-Hose Tri-Flex Loop

Flex-Hose Tri-Flex Loop

Flex-Hose Tri-Flex Loop is Available from N.H. Yates

It doesn’t matter what region of the country you live in, your buildings and structures are susceptible to damage from seismic activity. In fact, FEMA has identified mechanical failures of gas and water lines as one of the main causes of fire and damage to property during a seismic event. Fortunately, the Flex-Hose Tri-Flex Loop was created to absorb and compensate for ground movement in six degrees of freedom (three rotation axis, plus rotation along those axes simultaneously). This multi-plane movement design can reduce the need for expansion devices required in piping systems up to 50%. In addition, the Flex-Hose Tri-Flex Loop is the safest and most reliable means of absorbing movement resulting from thermal changes and random seismic shits in a piping system.

Why Choose the Flex-Hose Tri-Flex Loop?

Flex-Hose Tri-Flex Loop

First, Flex-Hose simplified its piping design for an easier installation process. The Tri-Flex Loop does not impose thrust on the piping system. Rather, the pipe’s braid is designed to take the stress of pressurization containing the core, which reduces anchor loads up to 93%. The Tri-Flex Loop also eliminates the need for pipe guides required by traditional pipe designs. Second, the Tri-Flex Loop increases usable space and reduces systems cost. The Flex-Hose system uses 64% less space than mechanical loop systems and eliminates the need for six welds during installation. Additionally, fewer fitting and welds are necessary if the installer positions the Tri-Flex Loop at directional changes and rotates the elbows to make a connection. Third, the Flex-Hose is approved to use in a variety of applications including compressed and combustible gas, steam, hot water, condensed water, and domestic water systems. To accommodate the Tri-Flex Loop is available with flanged ends, steel made NPT ends, weld ends, grooved ends, copper female sweat, or press fit ends.

Maxitrol EXA Star Modulating Valves

EXA Star Modulating Valves

Maxitrol EXA Star Modulating Valves

Modulating control valves change the flow of fluids, pressure, level, and temperature control of a system. Most modulative values are made up of three main parts: a valve body, an actuator, and a positioner. The positioner, through the actuator, drives the valve based the setting of the control signal. The Maxitrol EXA Star Modulating Valves are equipt with a built-in digital controller that gives a seamless interface with a process controller. The valve has two buttons and a communication LED for the user interface which is used to set the valve for high and low fire settings. In addition, the valve has full open and full close mechanical limits. This feature adds dimension for sizing and applying is significant because it allows the valve to be set up for an entirely different net output depending on pressure supply. The EXA Star Modulating Valve has six electronic connections – two for the power, two for the control signal, and two for the position feedback.

Linear Maxitrol EXA Star Modulating Valves

EXA Star Modulating Valves

Maxitrol’s E42, E52, and E62 Series EXA Star Modulating Valves are designed to have a linear relationship between the control signal and flow rate. This flow rate linearization will optimize over a 5:1 turndown ratio with the maximum flow rate determined at 1″ w.c. pressure drop. With applications in areas with atmospheric low-pressure, these modulating valves consistent gain allows the controller’s entire signal range to be utilized and tuning is simplified. This is a significant improvement over traditional designs. Rather than using a ball, butterfly, and poppet valve, the EXA Star modulating valve has a built-in digital controller that provides a seamless interface with the process controller. This allows the installer to set the high fire and low fire settings and establish mechanical limits for the valve.
