Why Dedicated HVAC Systems Are Better for Your Facility

on Posted on

For the facility’s unique processes and requirements, your team has designed and optimized every aspect of your operation. This optimization has become a minimum requirement for continued operation. But utilities and your HVAC systems are often thought of as ancillary systems. They become outdated and even neglected, despite this optimization of processes.

For facility leaders, minimizing or eliminating any process interruption is always top of mind. And you must ensure that regulatory and safety requirements are met at all times. As a result of these and other operational pressures, you probably undertake frequent routine maintenance if you have an aging facility system. For you, these aging systems with like-for-like replacement lead to increased labor investment, higher operational costs, and shorter total system lifecycle.

Production processes and technologies have changed

Many facilities’ current boiler-driven process systems barely resemble their original design. Increasing the size of these systems to handle the heating requirements as well as the process loads added massive complexity and simply doesn’t make sense today.

Instead of investing incrementally in an antiquated system, it is far more efficient financially and energy wise to take advantage of the dedicated system technology available today. Rather than continual reactive fixes, a proactive plan pays big dividends for the entire operation, from production efficiency, to air quality, comfort level, and more.

By retrofitting your existing heating, ventilating, and process steam systems with right-sized and right-located dedicated systems, you can:

  • Reduce energy costs
  • Reduce maintenance costs
  • Reduce operating costs
  • Reduce asset replacement costs
  • Reduce system complexity

 Dedicated space heating is better

 Dedicated direct-fired High Temperature Heating & Ventilating technologies like the Cambridge S-Series can provide the most cost-effective way to meet comfort requirements year round. With 20% to 70% energy savings, flexible installation configuration, and minimum operations interruption, these dedicated systems can be used to solve a myriad of problems.

Dedicated makeup air is better

 Dedicated direct-fired natural gas Outside Air Units (makeup air units) like the Cambridge M-Series provide extreme efficiency and effectiveness to solve complex building pressurization problems. Left unresolved, these pressure challenges could cause comfort, process, or indoor air quality problems. With full gas modulation and optional Variable Frequency Drives, the M-Series ranges from 1000 CFM to 100,000 CFM and 100MBH to 9000MBH, meeting the toughest of ventilation requirements.

Once you have dedicated systems handling the space heating and ventilating loads, your team can concentrate on meeting the unique process needs with the most energy-efficient and code-compliant boiler. Additionally, since the process load has been isolated, you can run the boiler at a more consistent operating window, raising the efficiency even more. Minimizing the size of this unit significantly decreases maintenance cost and complexity with fewer steam traps, steam leaks, and miles of pipes to manage.

By embracing cutting-edge dedicated systems technology, facility leaders can spend less initially to purchase and install right-sized boiler systems. Additionally, you will realize ROI quickly with lower energy consumption and operating costs, as well as longer system lifecycle.

Why HTHV Is Advantageous for Heating Industrial Facilities

High Temperature Heating & Ventilating (HTHV) direct-fired 100% outside air technologies

HTHV with High Velocity Blowers provides destratification. Temperature stratification is a major issue in all high-bay industrial applications in the wintertime and must be addressed through the proper selection of destratification technologies. A recent study published by the Department of Energy titled Field Study of High Efficiency Gas Heaters looked at the energy savings accomplished with HTHV 100% outside air direct-fired technologies. The report states: “As evidenced by the temperature readings near the floor and ceiling, the new (Direct-fired 100% Outside Air HTHV) gas heaters reduced stratification, maintained more uniform temperature distribution, and consumed 20% less natural gas.”

HTHV provides continuous or intermittent control options and heating and ventilating in a single unit

Direct-fired 100% outside air systems provide controls to operate either continuously or intermittently based on occupancy schedule, process conditions, pressure, or any number of other control requirements. There are actually three primary modes of operation for these HTHV 100% Outside Air Technologies:

  • Ventilation/Exhaust Replenishment
  •  Space Heat & Ventilation
  • Space Heat

 HTHV provides pressure control design flexibility

There are many different ways to pressure control a building. 100% outside air direct-fired technologies are completely capable of being controlled at positive, negative, or neutral pressure. There is significant debate on what is the “best” pressure control methodology for a building in the winter. Negative reduces risk of condensation, and positive decreases draftiness. However, both methods increase energy consumption over neutral.

The HTHV technologies have become the gold standard for energy-efficient industrial warehouse heating in North America over the past 20 years. These technologies are now being launched into the broader commercial heating and ventilating market because of their energy efficiency and low installed costs.

The 100% outdoor air introduced through ANSI Z83.4 technology is designed and installed to improve the indoor air and environmental quality of the facility. Any level of required ventilation, including ASHRAE 62.1 levels, can be achieved and maintained through these technologies. Many offerings include optional MERV13 filters added to the inlet air of this device, further improving indoor air quality. ANSI Z83.4 equipment can be installed with a minimum amount of ductwork, providing an efficient and cost-effective installation. Additionally, the technology can be installed indoors or outdoors or in horizontal or vertical configurations, permitting added flexibility while always providing 100% fresh outside air.

Recognizing the Complexity of Industrial HVAC, Process Manufacturing, and Process Requirements

on Posted on

Industrial facilities today don’t have to be new in order to be efficient

Leading facility owners and operators are retrofitting existing facilities into models of efficiency and sustainability. Industrial facility retrofits are investments in efficient technologies that span all facility systems, including lighting, facility envelope, and HVAC. While most facility owners still pursue single technology improvements, market leaders bundle together energy saving technologies in a more comprehensive approach to get deeper savings and greater lifecycle value.

 

 

Challenges for facility leaders are complex

Facility leaders recognize that industrial retrofits are largely about managing risk.

Each facility project is unique and distinctive. Implementing a retrofit while protecting the production capabilities within the operation creates high visibility and requires a very clearly defined plan. Minimizing and eliminating all business interruption is always a top priority. It is also essential to protect the organization and meet or exceed all regulatory mandates to ensure safety for people. Facilities leaders seek trusted advisors and working arrangements that are in sync with all regulatory guidelines for facility compliance.

This complexity can result in a built-in resistance to efficiency retrofits and change. For this reason, facility retrofits are often conducted in a reactive versus a proactive mode. “Like-for-like” system replacements are the most expedient directive when reacting to a facility system failure or needed upgrade. However, with superior options available, these short-term decisions can result in not only higher upfront costs but also dramatically higher operational costs and shorter total lifecycle of systems selected.

Aging mechanical systems and equipment require asset-replacement planning

Various aging facilities systems drive more frequent routine maintenance and require more people resources to maintain, which increases operating cost. Aging facility assets are a reality. Planning for and developing a methodical aged asset replacement strategy requires leadership planning and trusted partner relationships in order to benefit from system expertise applicable to your unique facility requirements.

 Systems interdependence impacts scalability

Industrial facilities evolve over time to reflect the changing needs of growing industries, modern equipment and processes, and other economic trends. In many instances, current production systems and technologies barely resemble their original form. Their supporting systems are often overlooked. As production systems change, there is a direct interdependence to process loads and exhaust systems. When HVAC systems are overlooked, this can cause inadequate makeup air, negative pressure problems, cold spots, and overall poor comfort levels.

Furthermore the infrastructures of these aged industrial facilities typically resemble single systems that serve multiple functions, thus hindering their ability to scale their production rapidly and efficiently. Facility leaders are left with difficult decisions when incremental changes in production capacity become less cost-effective because of inadequate, interdependent systems.

Facility leaders have many reasons to seek functional expertise and consultation to build proactive plans:

  • The need to meet or exceed corporate energy reduction mandates
  • To exceed production capacity metrics
  • In order to provide labor with ideal environment conditions: people comfort, productivity, and facility thermal condition requirements
  • To meet all facility safety regulations

Facility HVAC systems support improved process and production capacity

Facility leaders considering industrial retrofits of HVAC systems recognize the value of:

  • Rapid ROI – multi-level corporate approvals
  • System reliability and durability
  • Lifecycle cost
  • Standardization for proactive management and metrics
  • Integration with building automation systems
  • Complementing production and process applications of HVAC systems
