At Pinnacle Equestrian, careful attention to the most minute detail is standard procedure.  Even the sand in the facility’s jumping arena is specially shipped in from Utah for just the right granularity and compression.  Laser-leveled to perfection, the sand is regularly monitored for moisture content to ensure the highest level of safety for horses and riders.

Pinnacle Equestrian is a privately-owned Olympic-level equestrian hunter-jumper facility in the scenic Sonoma Valley, Calif.  Owners Ron and Lauren Silva cater exclusively to Pinnacle Equestrian’s hunter-jumper clients.

Client horses warm up at the facility before competing in such events as the Longines FEI (Fédération Equestre Internationale) World Cup™ circuit’s annual Sacramento jumping qualifier which attracts the world’s top riders.  As for the up to seven young resident horses that do call the property home, they’re in training for future competition.  When ready, they’ll eventually be sold to new owners.

Pinnacle Equestrian trains horses to jump exclusively in the Grand Prix range (1.4-meter to 1.6-meter or 4.6’ to 5.2’).  These heights represent the “pinnacle” of the sport and illustrate the advanced nature of the Silvas’ operation.  “Pinnacle really sells itself based on our high-quality standards, how we care for the horses and what we provide World Cup circuit riders who warm up at our facility,” explained Ron Silva.

Challenge

Provide an effective airflow solution within a round equestrian barn to maximize horse and staff comfort while complementing the barn's interior aesthetics.

Solution

An 18-foot diameter Entrematic I-Class™ industrial HVLS fan mounted to a glulam beam complete with custom-designed wrought iron images of jumping horses.

Impact

9,800 cubic feet of air that's replaced every 90 seconds ensuring the year-round health, safety, and comfort of resident horses in training as well as staff.

Horse stalls and box fans: a bad combination

The focal point at Pinnacle Equestrian is the property’s stunning and rare 16-sided, tongue and groove ash round barn where horses stay at night and are tacked and groomed each day.

The European-style, 5,200 square-foot barn is sited so that interior temperatures are consistent throughout all seasons.  Only when oppressive heat builds due to changes in westerly breezes — normally nature’s air conditioning in the region — is when things get uncomfortable.  Each of the barn’s ten stalls has a window for ventilation and to capture ambient breezes.

However, when outside temperatures reach 90 to 95 degrees, the horses can become sluggish and uncomfortable.  As a result, serious concerns about stress come into play as well as equine colic, a digestive system disorder that can be life-threatening.

“To help alleviate heat stress, we originally used 10 box fans and hung them on stall doors with plastic wire,” explained Lauren Silva.  “But, they looked really bad in such a beautiful barn and were really quite dangerous.  Plus, it’s very bad to direct air movement right on horses at such a close distance.”

She added that the fans were also drawing in dry air from outside, ran too fast and the pitch of the fans’ noise was not conducive for their horses.  “When Ron saw the fans operating, he immediately knew they weren’t working and quickly determined we required another approach because box fans definitely weren’t the solution we needed.”

According to Ron Silva, one of the most alarming reasons that box fans weren’t the answer is that they don’t have sealed motors.  “You should never run fans in a barn without sealed motors,” he stressed. “We use wood shavings for bedding and the box fans only stir them up along with adding fine particles in the air that get into the horses’ eyes, causing drainage and discomfort.”  He added, “All combined, it’s quite a fire risk to have wood shavings landing on unsealed hot motors.  In addition, all of the cords hanging around were dangerous trip points and relying on 110v power is not very inefficient.”

The quest for a better air movement solution

Ron Silva then began to research high- versus low-velocity air movement as well as various HVLS (high volume low speed) fan manufacturers in a quest to find the perfect solution.  Relying on the expertise of Entrematic’s Dan Linder, Sales Manager, HVLS Fans, the solution for Pinnacle Equestrian became the company’s 18-foot diameter I-Class™ HVLS fan mounted directly below the barn’s cupola.  The fan, with its blades 20 feet above the barn floor, is mounted on a glulam beam that features waterjet-cut wrought iron images of two jumping horses on either side.

“I really liked the fan blade design, which made the most sense to me for moving just the right amount of air,” Ron Silva pointed out.  “The fan blades, design, material and weight far surpass what the competition has to offer.”  He further explained that due to the barn’s aesthetics, he and his wife did not want to use guy wires that are needed at higher operating speeds to eliminate rotational vibration.

“Entrematic was able to work with us on the proper bracing needed to accomplish what we needed without guy wires.  Our approach works fine as long as we don’t exceed a certain RPM operating speed.  In the best interest of our horses, our intent is to move a high volume of air slowly without creating a breeze sensation and to also lower the round barn’s temperature without inducing humidity,” he said.

A much better customer service experience

While exploring another major manufacturer of HVLS fans, Ron Silva related that his experience did not go well.

Ron Silva stated that one of the most important reasons he chose Entrematic is because one competitor’s customization claims are simply false.  “They say that they’ll accommodate you, but that’s not the case,” he explained.  “Functionality and appearance were very important to us, and we wanted the total capability to customize and handle our own installation. The competitor said that would void our warranty unless they installed our fan.  We didn’t have the confidence they would be willing to stand behind the warranty if we installed the fan ourselves.

“Entrematic was really willing to work closely with us, whereas the competitor would not even consider talking to us about how we wanted to use their product,” Ron Silva continued.  “All around, Entrematic was much more pleasant to work with and answered all of our questions.  Our customer service experience with Entrematic was superior in every way.”

Ron Silva related that when he started researching HVLS fans, he worked on his own calculations to determine the needed fan diameter and how much cubic feet of air needed to move over a given period.  The Entrematic fan empties out and replaces the barn’s 9,800 cubic feet of air every 90 seconds.  “I’ve found that the fan can really overcome any efficiency in structural design,” he added.  “In our case, the fan supplements the barn’s round design and built-in airflow characteristics really well.”

Vastly improved working environment

The time of year determines which direction the blades rotate.  In the summer, the fan pushes hot air down and out through 10 barn windows and other openings to create a cross current while drawing in outside air through six powered windows in the cupola.  The reverse is true during the winter when the fan draws in fresh air through the barn windows and then pushes the air up and out through the cupola.  The fan doesn’t necessarily change the barn’s temperature, but it does but make the barn environment feel much better to work in.

“During colder weather, we keep the horses blanketed, but we try not to baby them too much,” Ron Silva said.  “Running the fan in reverse, we’re more interested in improving the barn environment than actually heating the barn.”  As a rule, the barn never drops below 50 degrees.

Ron and Linda Silva further shared, “Entrematic was willing to work with us in such a way that only a small percentage of the market (2-5%) would ever require.  The company’s competitors essentially offer you a ‘here’s our fan, take it or leave it approach’, which may satisfy 95% of the market.  The question remains, who’s willing to work with the remaining 5% of the market like us?  Entrematic was willing to do just that.”
