Let’s Dive into Harris Calorific Multistage Gas Regulators 3302659
The Harris Calorific Multistage Gas Regulators 3302659, manufactured by Harris Calorific, promises consistent and accurate gas delivery for critical laboratory applications. This regulator is designed to maintain stable working pressure even with fluctuating inlet pressures and varying flow rates, essential for gas chromatography and other sensitive processes. I was intrigued by its multistage design and the claim of minimizing regulator damage from contaminants, hoping to solve a recurring problem with inconsistent readings and equipment downtime.
For years, our lab struggled with pressure fluctuations that skewed results and required frequent recalibrations. We were constantly battling the insidious creep of tank scale and rust that compromised our existing single-stage regulators. The allure of a multistage regulator, especially one built with the reputation of Harris Calorific, was too strong to ignore.
Upon unboxing, the Harris Calorific Multistage Gas Regulators 3302659 felt solid and well-engineered. Its brass body exuded durability, and the gauges were clear and easy to read. It was heavier than our previous regulators, a sign (I hoped) of robust construction and quality components.
We had been using a generic single-stage regulator and a competitor’s two-stage model before. The generic one was too unstable for precise work, leading to large errors. The competitor’s model, while better, still exhibited some pressure drift, and its construction felt less robust. The Harris Calorific Multistage Gas Regulators 3302659 seemed a step up in both build quality and design, specifically addressing our need for consistent delivery pressure.
My first impression was cautiously optimistic. The robust construction and detailed specifications suggested it could be the solution we needed. However, the true test would be in its performance under demanding laboratory conditions.
Real-World Testing: Putting Harris Calorific Multistage Gas Regulators 3302659 to the Test
First Use Experience
I tested the Harris Calorific Multistage Gas Regulators 3302659 in our analytical chemistry lab, specifically connected to our gas chromatograph-mass spectrometer (GC-MS) system using an industrial oxygen mix. This system demands extremely stable gas pressure for accurate and reproducible results. Initial setup was straightforward, thanks to clearly labeled ports and standard CGA 296 fitting.
The regulator performed flawlessly under consistent flow demands. The delivery pressure remained remarkably stable, even when the supply cylinder pressure dropped significantly. There was no noticeable drift or fluctuation, even after several hours of continuous operation, a stark contrast to the struggles we had with other regulators.
The initial use was a complete success. The stability provided resulted in immediate improvement in the consistency and reliability of GC-MS analysis. This eliminated the need for frequent recalibrations and reduced the time spent troubleshooting pressure-related issues.
Extended Use & Reliability
After several months of continuous use, the Harris Calorific Multistage Gas Regulators 3302659 continues to perform reliably. There are no signs of wear and tear, and the gauges remain accurate. The solid brass body shows no corrosion or degradation despite continuous exposure to industrial gases.
Maintenance has been minimal. Periodically wiping down the exterior and checking for leaks is all that’s been required. The sintered inlet filter effectively prevents particulates from entering the gas stream.
In my experience, this Harris Calorific regulator significantly outperforms its predecessors in terms of stability, reliability, and ease of maintenance. It has noticeably reduced downtime and improved the accuracy of our gas chromatography analyses. The Harris Calorific Multistage Gas Regulators 3302659 is a tangible improvement over the less robust regulators we previously used.
Breaking Down the Features of Harris Calorific Multistage Gas Regulators 3302659
Specifications
Gas: Industrial Oxygen Mix. This specificity ensures optimal compatibility and safe operation with the designated gas.
Inlet CGA: 296. This connection type allows direct and secure attachment to compatible gas cylinders.
Flow Capacity, Standard CFH: 1700. This high flow rate allows for demanding applications without compromising pressure stability.
Delivery Range, psi: 0–125. This broad range allows for fine-tuning of the outlet pressure to meet different experimental requirements.
Delivery Pressure Gauge, psig: 200. This gauge helps users monitor the delivery pressure accurately.
Supply Pressure Gauge, psig: 4000. This gauge indicates the pressure inside the gas cylinder.
Unit: Each. Indicates that the product is sold individually.
Valve Outlet: 0.6 cm (1/4“) NPT. The standard thread size makes it easy to connect to a variety of instruments and equipment.
Body Outlet: 0.6 cm (1/4“) NPT. This outlet mirrors the valve outlet allowing for consistent connections.
The multi-stage design featuring two internal regulators is key. The first regulator reduces the cylinder pressure to 90%, enhancing safety and reducing stress on the second regulator. The second regulator then provides precise control of the delivery pressure, maintaining a stable output even as the cylinder empties.
The stainless steel diaphragms offer excellent chemical resistance and durability, minimizing the risk of corrosion or degradation. The PTFE encapsulated seats further enhance sealing and prevent leakage. The sintered inlet filter prevents particulates, tank scale, and rust from entering the gas stream, protecting the regulator and downstream equipment from damage.
Performance & Functionality
The Harris Calorific Multistage Gas Regulators 3302659 excels in providing stable and accurate gas delivery. Its ability to maintain constant working pressure even with fluctuating inlet pressures is crucial for sensitive applications like gas chromatography. The regulator’s reliability and ease of use make it a valuable tool in any laboratory setting.
The primary strength is its exceptional pressure stability. A notable weakness is that it’s designed only for noncorrosive gases. The regulator meets and exceeds expectations for pressure stability and consistency.
