2 Year ROI

The average return on investment period for an Eco-Flow-C® drive is less than 2 years.

 

so smart, yet so simple

Eco-Flow-C® combines functionality, quality, and reliability to provide the user with an unparalleled VFD experience. Fully configured for the pool & spa industry, Eco-Flow-C® offers an array of unique features to ensure complete optimization of pool pumps while also maintaining ease of operation and user-friendliness.

Designed for 3-phase centrifugal pool pumps ranging from fractional thru 1,500 horsepower, Eco-Flow-C® Aquatic Variable Frequency Drives are capable of handling practically any recreational water application, e.g., pools, spas, fountains, and various other types of water features.

Eco-Flow-C® Aquatic Variable Frequency Drives are backed by our combined 100-plus years of experience with monitoring and controlling pumps.

what makes eco-flow-c® different?

VFD’s are designed for a vast array of applications. It just so happens that aside from its very harsh environment, the commercial pool room is one of the more simple applications that a Variable Frequency Drive can be used on. However, no VFD manufacturer currently produces a product that is ‘specific’ to this application. There are, therefore, literally hundreds of parameters that the end customer will need to understand when setting up the product.

Eco-Flow-C® changes all of that! Eco-Flow-C® uses a unique Aquatic Controller that allows customers who have never even seen a VFD before, to get up and running in less than 15 minutes.

unique aquatic controller

Using a vivid color touch screen display, the Eco-Flow-C’s® unique Aquatic Controller provides an unrivaled user experience. Programming the VFD is achieved by simply answering a small number of simple questions. Day-to-day operation such as pump start, pump stop and backwash speed control are initiated with a simple push of a related command on the screen. With the inclusion of the Eco-Flow’s® optional Flow Transducer, the Aquatic Controller even provides a digital readout of flow (GPM).

 

constant flow

While running the pump at a lower speed will achieve a significant reduction in operating costs, Eco-Flow-C® can further optimize the circulation system’s performance by utilizing its powerful ‘Constant Flow’ feature. Precise control of the flow rate will ensure that the State’s mandated turnover rate is maintained – even as the filter becomes dirty. As an added safety measure, the system will not allow the pump to over-speed and will go into a visual alarm condition should it determine that the filter needs to be backwashed.

Eco-Flow-C® makes energy savings of 40% or greater possible!

 
Washtenaw is saving tens of thousands of dollars every year by installing VFD pump control systems at its public pools.

Energy efficiency measures undertaken by the City of Santa Monica in 2012 include: using a Variable Frequency Drive to control water pumps at the city aquatic center.


Built for Purpose

The hostile environment of a pool equipment room is not ideal for a typical Variable Frequency Drive – unless it’s a NEMA 12 rated Eco-Flow-C®.

The vast majority of VFD’s are NEMA 1 rated and designed for clean, dry, non-corrosive environments, which is not typical of most pool equipment rooms. Over time, chemical gases will destroy electronic circuits that are not fully sealed and protected from such an unforgiving environment.

It is essential that the VFD’s electronics be fully sealed and protected against these effects. For more than 30 years, H2flow and its partners have been exposing VFD’s to some of the harshest environmental conditions. You can count on us to protect your investment.

 

Eliminate water hammer

Starting and stopping pumps often results in ‘water hammer’ a phenomenon associated with a pressure surge or wave caused when a water motion is forced to stop or change direction.

Water hammer commonly occurs when a pump is started or stopped and a pressure wave propagates in the pipe. It may also be known as ‘hydraulic shock’. This pressure wave can cause major problems, from noise and vibration to pipe collapse.

By ‘soft starting’ and ‘soft stopping’ the pump, Eco-Flow-C® will completely eliminate water hammer and any risk of damage associated with it.

 

PUMP PROTECTION

Eco-Flow-C® features a unique and patented ‘Load Curve’ monitoring feature that protects the pump and system from abnormal operating conditions.

During its ‘AutoSet’ procedure, the system automatically measures the shaft power taken at nine incremental points between the minimum and maximum speeds to be used. From these measured data points, the system creates a ‘normal’ pump curve and applies both overload and underload protection in order to detect abnormalities such as closed valves, cavitation, worn impeller, run dry, loss of prime, bad bearings, etc.
