Pressure drop impacts everything—from energy consumption to product quality. As throughput increases, adding Votator® II Scraped Surface Heat Exchanger (SSHE) units in series can raise system pressure, placing added strain on pumps and process equipment. 

The Votator II pressure drop reduction configuration is designed to solve this. By optimizing internal flow, it reduces resistance across the scraped surface heat exchanger and entire process line—improving system stability, supporting pump performance and enabling more efficient operation in demanding applications.  

**Ideal for:**

- **High-viscosity products** where pressure drop and product shear must be carefully managed
- **Multi‑unit Votator II installations** requiring multiple heat exchangers in series
- **Clean‑out‑of‑place (COP) environments** with lower‑rated upstream or downstream equipment
- **Retrofit and upgrade projects** where improved performance is needed without full system replacement
- **Typical applications** include, but are not limited to, meat slurries, pet food processing and industrial oils

### Find out how the Votator II pressure loss reduction configuration can work in your process.

#### Designed to Reduce Pressure Drop

#### 3" Shaft Design

A reduced shaft diameter increases the annular flow area inside the scraped surface heat exchanger. This improved flow path **reduces pressure drop across the heat transfer zone** while maintaining effective heat exchange performance.

#### 4" Product Port Connections

Larger product port connections encourage the use of larger piping throughout the system.  Because pressure drop is inversely proportional to pipe diameter, this design helps **reduce system‑wide pressure losses and improve flow efficiency**—from inlet to outlet.

#### Why Reducing Pressure Matters

#### Stabilize Your System as Capacity Grows

Adding scraped surface heat exchangers in series increases available surface area—but it also raises overall system pressure. This can limit equipment selection and place unnecessary stress on upstream and downstream components.  By reducing pressure loss, you can **maintain stable operating conditions** and protect critical equipment.

#### Optimize Pump Performance

Votator II SSHE are typically fed by a positive displacement pump, such as the **WCB Universal 1**, often operating within pressure limits of 150–200 psi. Managing pressure drop is critical to staying within these limits. Reducing pressure loss helps improve pump efficiency, minimize mechanical strain and support reliable operation—particularly in clean‑out‑of‑place (COP) environments.

#### Lower Line Pressure and Product Shear

The pressure loss reduction design enables the use of **larger‑diameter interconnecting piping**, reducing fluid velocity throughout the system.  This lowers overall line pressure, helps minimise product shear and and protects end-product quality, texture and integrity across a wide range of demanding processes—especially in **high‑viscosity applications**.
